Bug: Edge v104.0.1293.54 always unable to start after own update on v103.0.1264.77 (Stable)

Kelly_Y  Hello again,

1st of all apologies for so much delay occurred before this additional reply of mine (due to some unexpected OS freezes).

Even if I still haven't received any further reply to my latest post P.S. questions (About your reference to that Dev support area could you be more specific ? I mean were you considering 'Microsoft Q&A' side or just the 'Insider Program' side where it also says 'Get help, including email support, for the Microsoft Edge Insider Channels.' ?) at least now I'm again able to provide you (and possibly others interested too) that I would still like to receive, I can now update you again about my previously anticipated tests and my current status.

- About using 2nd self rollback method described by Andy Zeigler in his Ignite September 2020 video based on executing v103.0.1264.77 setup via standard MicrosoftEdgeUpdate.exe updates while all properly required Edge policy settings were also enabled: only after I manually enabled all 3 required  Edge v103.0.1264.77 policy settings I also discovered that same method could not have worked because my client was not inside a Domain (evidence of this was inside C:\ProgramData\Microsoft\EdgeUpdate\Log\MicrosoftEdgeUpdate.log where I also found this explanation ... [ConfigManager::LoadGroupPolicies][Machine is not Enterprise Managed]...). Due to this I also assumed that I would have likely needed to try to 'simulate' somehow being inside a Domain by only using OS group policies, but then I also figured out I could have not really been sure that doing so was indeed possible :-(( ;

- About manually running MicrosoftEdgeEnterpriseX64.msi v103.0.1264.77 using 'msiexec /I FileName.msi /qn ALLOWDOWNGRADE=1' syntax: I foud not enough spare time to try to ensure to definitely fix my client difficulties to install 64bit .msi programs only with Windows Installer (always failing) while 32bit .msi programs indeed always installed fine;

- About my current browser status: when on Tue 16th August I created this post I was forced to use latest Firefox Portable (v103.0.2.8255) but after some other unexpected OS freeze experienced while it was still running, on Sat 20th afternoon I found I could no more use it properly because of a weird error still unsolved ('Your Firefox profile cannot be loaded. It may be missing or inaccessible') even when starting it while also specifying its '-safe-mode' switch. Anyway same day in the evening I also discovered by chance that at least while in InPrivate mode, an Edge v104.0.1293.54 window could be opened properly (this happened after an IE11 InPrivate session, run with Admin privileges, displaying an embedded Youtube video on a local web site was redirected to another separate Youtube hosted site video that opened an Edge window using a very specific command line syntax I'm only partially logging here: "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --from-ie-to-edge=1 --inprivate ...). Then on Mon 22nd evening my client also received latest (& current) Edge v104.0.1293.63 and finally only today I could find enough spare time to repro same situation again always starting from an IE11 InPrivate session run with Admin privileges. So, after I displayed another embedded Youtube video, at the end I choose to see another one and again this opened a separate new Edge v104.0.1293.63 InPrivate mode window, once again using a very specific command line syntax that this time I can nearly fully log here (I'm just excluding involved Youtube video because it was not in English: "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --from-ie-to-edge=1 --inprivate --customer-type=1 --enable-features --disable-features --flag-switches-begin --flag-switches-end --do-not-de-elevate https://www.youtube.com/watch?v=<removed_since_NotInEnglish>&feature=emb_rel_end), and while that window was opened I also verified I could properly run Edge via its Quick launch application bar icon I manually created after dragging 1st Edge v92.0.902.73 self created icon from Start (menu) -> All programs (just for the records this is what it always runs '"C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" --profile-directory=Default') , and this also allowed Edge v104.0.1293.63 (Enterprise) to recover those same 2 standard Edge windows that were still opened while Edge v103.0.1264.77 (Stable) was still running before an unexpected OS freeze.

At this point here are my new questions to you (unless someone else might like to jump to reply and maybe add even more details) :

- Is what I experienced, I mean Edge v104.0.1293.54 or v104.0.1293.63 only starting properly while in InPrivate mode because of a very specific command line syntax execution, something that had to be expected because Edge was not yet really switched to be OS default browser ?

- Is there already any known reference documentation (i.e. maybe on MS Docs, rather than inside 1 or more MS Support KB articles) that can also confirm all valid command line options available for Edge and/or Edge Enterprise ?

P.S. Just to confirm that now I've been able to report all older dumps created by Edge v104.0.1293.54 via Edge Feedback opened from same 1st Edge v104.0.1293.63 InPrivate mode window opened yesterday.

ITMT I also :

- checked that so far no known MS Support KB article exists to confirm MS Edge all known or most likely used command line switches (so far I searched starting from 'Microsoft Edge help & learning' page <https://support.microsoft.com/en-us/microsoft-edge?ui=en-US&rs=en-US&ad=US>),

- tried to expand my investigation through bing to also look for "--from-ie-to-edge=1" switch usage but I still have to fully check results,

- can confirm you I received latest v104.0.1293.70 but I still have to manually restart Edge via its UI to complete its update.

Thanks in advance for any next reply.

Best Regards
