This is what it looks like, and it only seems to happen either at the end of a combat sequence or when transitioning between locations (randomly, yet frequently). It's installed on an external hard drive in a read only folder. I play on a Windows PC. It looks like an older XP model installed with Windows 11. This is from when i started the game over from the beginning (right after the battle sequence with the slime girl of the training mission). I've had a few other games using rpgmaker and got this error screen, but nowhere near as frequently.
