[MCL-26054] The Launcher Deleted All Of My Custom Installations

When I opened the Minecraft Launcher today, I realised it had somehow deleted all of my custom installations, no matter if they were modded or vanilla installations; every one except latest version and latest snapshot was deleted and this is really annoying as I have lost many important ones

Can confirm with beta MS Store Version of the launcher (V b.3.22.20-2.2.2)

It seems to even have deleted the profiles from the launcher_profiles.json and just kept the two default profiles. At least they are backed up in the .bak file
