Edge Dev won't load any pages

[Derek Noonan]

I've been using Edge Dev as my daily driver for almost 3 months. I've returned from holidays and now nothing will load (I'm using GChrome to type this up!).

Any URL or PDF file just gives a "This page is having a problem, try coming back to it later" (even the edge:// pages)

I've uninstalled the version, deleted the User Data folder and re-installed the latest version but still no joy.

I spoke with Gabriel P, and, because it's a domain joined machine with Symantec Endpoint Protection he referred me here.

How can I help you out here? Developer, so comfortable taking memory dumps etc.

The beta channel install works, just not the dev one. Using this instead as some Edge is better than no Edge ;) It'd be nice to know a reason for it though

Hi @Derek Noonan, there was another thread with people discussing a very similar issue.  It appears that it might have something to do with the Symantec Endpoint Protection plug-in that you are using.  You can read how the other Insiders are dealing with this here: https://techcommunity.microsoft.com/t5/Discussions/This-page-is-having-problems/m-p/816671

@Elliot Kirk Many thanks for your response. I will try the approaches outlined in the linked post tomorrow and leave another reply.

Alright so the --disable-features=RendererCodeIntegrity switch works. Two questions out of this:

1. What changed within Edge that caused this negative interaction with SEP, and will it be tracked and fixed for release?

2. How do you know what switches are pertinent to a given issue? I found the full list of Chrome switches but maddeningly permitted options for (kDisableFeatures | kEnableFeatures) are not easy to find. In base_switches.cc it just says that they're a comma-separated list of feature names to enable or disable
