Thank you
So I merged the lines regarding `ReleaseMeshDeformerInstances();` (but did not merged lines 1185-1191 UMeshDeformerInstance::FEnqueueWorkDesc Desc; since they were already there in 5.5)
and it did not fix it
Well, since last time I checked, it was working in 5.6, I’m not sure it’s worth investigating this issue too thoroughly though.
