I have a project that used to be in UE 5 Preview but is now UE 5.0 and when I hit play, the game works fine, but when I try to open the character blueprint, the whole engine crashes. The log seems to indicate there are .dll files missing. Research on this topic seems to have led me nowhere. I tried copying the files over to a new project and the same results happen in the new project. Other projects have not given me this error yet. Any idea how I can salvage this project? Thank you for your time.
You could try deleting the DerivedDataCache folder, I see some shader messages which are likely to be resolved when you do. Other problems might disappear as well.
PixWinPlugin: PIX capture plugin failed to initialize! Check that the process is launched from PIX.
Along with the top info:
LogWindows: Failed to load 'aqProf.dll' (GetLastError=126)
LogWindows: File 'aqProf.dll' does not exist
LogProfilingDebugging: Loading WinPixEventRuntime.dll for PIX profiling (from ../../../Engine/Binaries/ThirdParty/Windows/WinPixEventRuntime/x64).
LogWindows: Failed to load 'VtuneApi.dll' (GetLastError=126)

Points at some problem with WinPix. However, I have never heard of it…
Message at the bottom is the direct reason, it is an assert.
I deleted that one folder with all those assets with shader errors and now I can open the characters without crashing. I did not use those assets for anything, so I don’t know why those two things were in any way related. Some things are still a bit fishy, so I’m going to keep this thread open until I’ve done some more exploring. I feel like another crash is right around the corner.
No, I don’t have the assert issue anymore after deleting the files, and I forgot to look at the related post.
Now that I look at it, I see someone mentioned problem files. For me, the problem files were the Warning preceding the error, which all came from a folder containing assets I was not using anyway, mostly Missing cached shadermap messages. I deleted the entire folder and containing a whole lot of assets which I did not want, and the error no longer triggered. Really weird, since they should have not had anything to do with my Blueprints in any way whatsoever.
