returned non-zero exit status 3221225477 problem with Kohya lora training

Can the problem be that I have GTX 1050 ti 4 GB? (playing with options to lower VRAM usage does not help), When I play with settings I get the same thing but the last thing changes to returned non-zero exit status 1.

Start with the reported train_network.py command and the full error output around CalledProcessError, then check how this Windows run handles the GTX 1050 Ti, fp16, xformers, and AdamW8bit options. Reproduce with the supplied arguments if possible; done means identifying a specific cause or compatibility requirement rather than only confirming the non-zero status.
