Yesterday the launcher was working normally. This morning all of my profiles were gone; the launcher only showed the latest version and snapshot profiles. In the launcher log, I found the error:
[Error: 2025-11-08 13:44:06.128449572: KR4XStEDeRA=: PersistentReflectedStruct.h(57)] Data version 5 is greater than current version 4 but we don’t support downgrading.
[Warning: 2025-11-08 13:44:06.128460851: KR4XStEDeRA=: PreferencesManager.cpp(70)] Unable to load profiles file.
PreferencesManager.cpp(134)]
[Info: 2025-11-08 13:44:06.128752414: KR4XStEDeRA=: PreferencesManager.cpp(134)] Removed /.../launcher_profiles_microsoft_store.json
By comparison, yesterday’s launcher log reported at the same stage:
[Info: 2025-11-07 13:58:25.937402131: 4x/1RRUDQZE=: PersistentReflectedStruct.h(134)] Successfully loaded file: /.../launcher_profiles.json
I was able to restore my previous launcher_profiles.json from backups made on Nov. 4, and verified that it ends with
"version" : 5
}The launcher version is 3.22.8-2.3.2. According to the logs, the version has not changed in at least the last four days which implies this error was a spurious glitch.

Can confirm on MS-Store Beta Version (V 3.22.20-2.2.2)
Restoring the launcher_profiles.json from the .bak file fixes the issue
I’d be happy to share my launcher logs, but as I noticed in another report about the same issue, attaching my logs and the .json file seems to trigger the bot. Now the issue seems to be gone.
