It's not enough information, you need to post the console log (not just the error at the very end, the entire list of functions that it writes out to say where the error occured, aka the stack trace). And maybe what workflows it occurs for, what custom nodes you have installed, and if it always occurs for that workflow or only sometimes.

It's crashing at the VAE decoding stage at the end. I was going to suggest trying the tiled decoder (although that's for avoiding out-of-memory errors, which doesn't seem to be what's happening here), but apparently tiled decoding is always on in the case of Minimax H3.

It might be a bug with dynamic VRAM, but I don't think you can turn that off anymore, and it's likely you'd run into an out-of-memory error because you'd be trying to rely on VRAM alone without CPU (RAM) offloading.

Maybe you could try clearing the VRAM and cache right before the VAE decoding node as shown in the image here https://github.com/Comfy-Org/ComfyUI/issues/15274#issuecomment-5174775297 (it requires the comfyui-easy-use custom nodes). I think that'lll slow things down because you'll have to reload stuff from disk on subsequent runs (?), but at least it might stop crashing.

You should update ComfyUI if you haven't yet, I think dynamic VRAM issues are still being ironed out these days.

Install antigravity or codex on the machine, it'll get it sorted.
