Serious Bug of UE5P1

A serious Bug could make Level Map and Blueprint lost.

Start with Skeletal Mesh in Character Blueprint, I cannot select the one I made Animation Blueprint with.

After restarting of the whole project, the map file was lost, together with Character Blueprint and Animation Blueprint, only animations left in the project.

Happens in UE5 Preview 1.

If you want to have more information including videos or screenshots, please contact me.

The problem of losing map is that you have the problem of downloading ue5 preemptive experience version. Just uninstall ue5 preemptive experience version.

Got it Thank you
