Hi. Did you find a solution for this? I’m having thesame issue.
Hi,
Thanks for reporting and sorry for not having noticed your post before. The problem will be fixed in UE5.8.
If you have the ability to compile the engine, you can cherry-pick this specific change to address it : https://github.com/EpicGames/UnrealEngine/commit/2a4ac5784771637bf6493514a3f84b50c4b6b437
