Problem opening projects

An error appears when opening most projects. Projects can be opened 10 times. An empty project opens immediately. Reinstalled Windows and all drivers. Help me understand the cause of the error.

Assertion failed: ReaderPos + Num <= ReaderSize [File:D:\build++UE5\Sync\Engine\Source\Runtime\Core\Public\Serialization\BufferReader.h] [Line: 52]

Hey @aleks7kman,

Looks like your project may be trying to reference some deleted files. You may need to delete/remove your config folder to open the projects, however, that would mean resetting up a lot of controls, etc. Check out this thread that has a possible solution outside of deleting the config file:

You can also try and verify your engine version to see if that resolves the issue.

Let me know if any of these work for you!

Hey @aleks7kman!

Checking in! Was the above the solution you needed?
