Thank you very much!
You fulfilled my dream!
I always wanted to help veterans, even forum veterans. I can only imagine what you must have been through with such a high post count. You must have seen stuff that would make your stomach turn.
I’m glad you replied without reading my post and will gladly be ignored again so you could increase your post count.
I thank you for your service.
Ahem, I got actual help on Reddit.
For people that have ran into the same problem, which seems to affect all 5.4.x versions of UE, the issue is in the buggy Studio Telemetry plugin.
Once disabled, everything ran normally.
