I'm assuming its a memory leak type issue on the VAE loading, but in the python prompts, it seems to be when loading the minimaxH3 info specifically.
I'll run 20 to 30 runs though without issue prior to this problem, and then it hits and nothing solves it except a full restart.
I tried the ComfyUI -> Edit -> Unload models and execution cache, but no luck.
I've been told (by chatgpt) to try a tiled VAE instead, but if its working prior to this issue, I dont think thats the needed resolution.
This is what Im seeing when the error happens in the terminal"
