The only error I know which might happen is a generic can't draw bitmap error that I can't fix. Is this the error that you're getting?
I rarely get it, but it seems to happen more often on lower end systems with less memory, especially when a lot of pictures get loaded for animations for example. You should try playing the game using the Falcon-mkxp.exe which used optimized code that should make it run better on system and see if that helps with the crashes.
I checked v1.81 and the culprit should be the files in the attached zip (took them from the rgss3a archive and fixed the uppercase and lowercase letters).
With Kadokawa's Game.exe the crash would be random. Reads first the files from the "graphics" folder and then those from the rgss3a archive. In slow cpus should be easier to trigger (takes more time to retrieve them from the archive).
With Falcon-mkxp.exe should happen every time since it is case sensitive and treats them as different files.
ps. in the Graphics.zip are the correct files.
In the game the unarchived files are the problematic and those inside the rgss3a have wrong upper/lower case letters.
