Unexpected data loss for extensions, local storage, etc. in Edge Beta
I haven't found a similar report, and this is very unusual for me. A few days ago, after I opened Edge, I noticed that all extension icons became default (blank), but others looked fine. Soon more things became default (like asking for default browser), but history, bookmarks and tabs were kept. Eventually I noticed that all installed extensions' files were lost (the list was kept, but all "corrupted"), and the extension's data was also gone, including data that wasn't backed up. I noticed that folders like "User Data.CHROME_DELETE" appeared, which contained a lot of files, but it didn't seem to contain extension files and data. I have never switched Edge versions to other branches. Today, Edge doesn't start (hangs, seem more than 1 hour) for me, had to kill the process and restart, then I noticed that this was happening again. Many extensions are kept at this time, but some are "corrupted" again. It appears that all extensions data is lost again, the history is a few days ago, and was synced to retrieve some. Cookies is lost. At this time, in AppData\Local\Microsoft\Edge\User Data\Snapshots, I see "103.0.1264.71" (07-28) & "103.0.1264.77" (07-31) folders, contains backups of some important files. But I don't think this includes the extensions storage that I value most (including things like OneTab). Maybe something related for config: * In my config, the AppData\Local\Microsoft\Edge Beta\User Data is a symlink to AppData\Local\Microsoft\Edge\User Data, I don't remember the exact reason, but it was at peace in the previous few dozens of months. * C drive is occasionally less well-off, but I don't think this should cause data loss. * A few days ago, I moved out the Group Policy - Computers - CacheDir, and added the Group Policy - Current User - CacheDir (i.e. https://docs.microsoft.com/DeployEdge/microsoft-edge-policies#diskcachedir). It points to the same directory on another HDD. * Launch Enhanced Options and Windows Update, maybe related, possibly it starts Edge stable and causes some data migrations, and a big failure for backups. 104.0.1293.35 in Edge Beta's edge://version for now.
