I have problems opening the project in Rider/Visual Studio after updating from UE 5.5.3 to 5.5.4. Is there anyone having similar problems?

I think I solved the problem. It has been working fine for a few hours.
When the problem first appeared, I could not even create a new C++ project with UE 5.5.4 and I was getting the same error.

I did the following steps to solve the problem:

  1. I removed the Unreal Engine Rider plugins; \UE_5.5\Engine\Plugins\Developer\RiderSourceCodeAccess and UE_5.5\Engine\Plugins\Marketplace\Developer\RiderLink
  2. I opened the project in Rider and built it. Now it was both building and opening and working in UE Editor
  3. I copied the RiderSourceCodeAccess folder back to its original location and also rebuilt RiderLink (from Rider IDE) and I was back to normal.
