unreal engine 5 UE5 - libwvr_api.so' was not resolvable to a file when used in Module 'WVR'

[V-Prep Harry]

Hi, I am currently trying to launch my project to the vive focus 3 and i have managed this before however had to revert to a previous version and in doing so the project will now not launch and it displays that there a bunch of WVR undefined symbols, i feel like it might be an issue with the build.cs file but i'm really not sure.

@V-Prep Harry

Hey, It sounds like there was some mismatch in the generated files.

Close unreal, try deleting 'binaries' and 'intermediate' folders and rebuilding the project

 

Thanks,
Alex
