Hey! I have the same problem and haven't found a solution yet. Do you know how to solve this issue?

For me I found that everything works fine if I do not have any UXTools buttons in a level. However, when I add a blueprint that contains a button (e.g., UXTPressableButton via ChildActor) the packaged project won't open. The error log messages don't seem to contain any useful information.

Looking closer, I got the packaged project to start if I set the "AudioComponent" of the UXTPressableButton to "None".

This isn't a solution as then pressing a button causes it to crash. BUT, at least this might be pointing to some UE bug or Audio issue with HL2...

Update: Tried to complete remove the UAudioComponent from the source... and it won't load again.. IDK...
