The game recently started crashing when I spend a moderate amount of time in it, usually taking my other applications (web browser, Black Desert Online) with it. This started happening when I switched video cards from a gtx 1070 back to my R9 Nano (with the proper sweeping of drivers with DDU). Here is the link for the output file paste.

The way you describe what's happening it feels like you're running out of memory. If you bring up the task manager by pressing Ctrl + Shift + ESC and select the performance tab, and then run Yiffalicious in windowed mode, can you see what the memory usage looks like?
Edit: This is an error log that was in my Yiffalicious folder. I believe this one is different.
