Additional Notes
The video reference shows from openning the launcher to the problem, it does take time for it to load all asset library, can safely be skipped to 1:44
Let me know of any files, logs or whatever I can collect from the launcher that will help with this.
Note that this is after running the powershell script from this thread: Fab is not showing up anywhere at all. - #41 by ElenaNizhnik
Note 2 is that I already uninstall epic launcher, unreal, and deleted the %appdata%, vault, cach, and related folders before, and the problem just comes back after while.
There is also this thread, where multiple people report the same issue: Cant update any plugin after unreal 5.7.4 update - #23 by D4KiR
And a thread from 2025: Plugin does not update
