Unreal Engine 4.25 released!

I tried dragging some suspected offenders into a clean project and I believe I found a/the culprit blueprint. It seems to be my GameInstance blueprint, which explains why so many other files crash too when opened since a lot of them depend on GameInstance in some form. The only information I have to go by at the moment however is the following error: "Serialization Error: Action Needed - Corrupt data found, please verify your installation (which I of course have tried)
The editor then crashes and reveals this error in the crash log


Assertion failed: false [File:D:/Build/++UE4/Sync/Engine/Source/Runtime/CoreUObject/Private/UObject/LinkerLoad.cpp] [Line: 4838]

I still don’t really understand how it is considered to be corrupt since the same object worked fine in 4.25.3 but I’m researching this new info anyway.
