I did not upgrade version, it is the same project I worked yestoday. But I did install and enable NVIDIA DLSS plugin yestoday and it worked ok. I searched similar posts and reset my NVIDIA control panle 3d Settings but it did not help.

Hey @elaneinside!

So this person had this error (the code means something specific, so typically the issue is the same). Maybe they could provide some insight!

Error: Unhandled exception - EXCEPTION_ACCESS_VIOLATION reading address 0x0000000000000040

I’ve got this error which causes crash anytime the game mode is loaded. I must have some bad reference or something in there. I was refactoring and brought over some code from another class into the game mode, and this may have broken some references to interfaces or a global event dispatcher plugin I am using. Thats just a guess. I have version control and can just revert the thing, but it is still going to cost me a couple hours work. Is there any way I can pinpoint the exact line of code or…

Problem solved. It seems something wrong with my blueprints I lately worked on. I went to project folder and moved those uasset files out of project folder then problem solved. Although I dont know what exactly cause the crashing but at least I can open my project now.
