Thank you so much for your comment, it's very helpful. I'll look into how to fix the problems you've encountered. Regarding the "Downloads" folder, it often has a long file path (for example, C:\Users\Username\Downloads\GameName\). I believe some game engines, including Unreal Engine, can have trouble handling file paths that exceed a certain length or contain non-standard characters. Moving it to a simpler location (like D:\Games\) shortens the path and eliminates potential conflicts. That might be the reason; I'll investigate it further.
