I created a new project with ue 5.4.3 and created a binding and i noticed that now before the editor freezes, it displays the message: waiting for skinned assets to be ready (target mesh) and waiting for skinned assets to be ready (source mesh), which when i had tried with previous versions it didn’t happen (i think) and just then displays another message and freezes. Anyway thank you very much, i will continue my project even though i completely forgot how it worked lol
