Game crashes upon loading level.

[PRYZMwubs]

Hi there, our game crashes upon trying to load a level. It doesn't crash when the plugin is disabled. I'm using the marketplace build. The plugin worked fine until recently. This was on UE 4.27.

The log is as follows:

UPDATE: Tried the github branch and I get the same problem. It works fine when loading the main menu but when trying to load any other level it crashes with Unreal stating "fatal error."

I don't think this relates to the Async Loading Screen plugin. Try to disable the plugin and Launch again to see if there is any crash. Also, delete Binaries/Interrmeridate/Saved folders then try again.

I already tried that. The game loads correctly without the plugin. It is 100% a problem with the plugin.

UPDATE: Just to be thorough, I did delete the Binaries, Intermediate and Saved folders and I still get the same problem.

Can you run this plugin in a new project on your PC to see if this bug happens again? Sorry, I can't help you if I can't reproduce this issue on my side. As I've researched, it may relate to unsupported renderer API. Try to change to Vulkan, DirectX11, OpenGL.
