Getting error window in complex projects

Hey all,

I was hoping to find a solution about the issue here. Whenever I work on big complex projects a window pop ups randomly and sometimes the background is getting black and Animate wont let me close the window. Once I close it using enter hotkey it pop ups again endless. The only way to fix this is to restart the project and the bad thing about this is I cant even save the project anymore. The file size is right now almost 500MB. Idk if Animate even can handle that but please don't tell me to update my driver or anything else because its not my computer. I have a high end gaming PC with 64GB RAM and all needed specs so im sure the issue is itself on Animate.
