Good morning,

Today i was unable to start my project anymore, because no more space on the C: drive, so I followed this video to modify my cache emplacement.

After changing in the EpicLauncher and in the Unreal editor preferences, my file took 30min to start. Once started, and after having all the build levels, and the shaders compiled, I restarted and the same thing; 30 min boot up, sounds don’t work, and VR doesn’t work.

So I put the caches back in their place, and in Epic and in Unreal… Despite everything, each time I restart, the project seems to reload everything from zero and the sounds even added just now. don’t throw.

Does anyone have an idea to help me?
