Ran into an odd issue with VS 2022 today where intellisense refuses to work only on new files with USTRUCT. Just adding one new file causes 8000 Unreal Build Tool intellisense errors while the project still builds fine.
…
VS17.7.2 / VS17.9.6, UE5.2.1.
Tried:
Removed UE VS integration plugin.
Verify engine files, verify VS.
Delete VS related files from project, delete binary / intermediate / cache folders from project and plugins. Deleted Temp, Deleted VS model cache, roslyn cache.
Uninstalled VS Unreal IDE support component.
Recreated VS browsing database… restarted PC. Recreated project files with VS 2022. cleaned solution. Built solution.
Build works fine, just STILL the same issue with intellisense. It goes absolutely nuts making my CPU spike to 95% at times and simply not working on any newly added file. Such strange behavior.
Is there any other cache to delete or data to verify?
The only actual error I see on startup is of the new integration feature… which seems the default now. It says “Some issues detected in UE configuration”. Wel great. WHAT issues, log where? I might just want to turn this off entirely, since it won’t be detecting the blueprints outside of VS project scope that use these c++ classes.
