Has some problem with training lora

When start training it gives me this error on old version after reinstallation all works as it should on new one have this its fresh reinstallation so i it shouldn't give such errors my guess the problem in U net since i read that training works only for new SDXL as i understand and where to install reinstall old version of Kohya for training on SD 1.5 i don't know or at least what version i need so it work like in old times

The report mentions LoRA training, SDXL, SD 1.5, and an error image, but names no source file, test, or entry point. Start by reproducing the error with the reported old installation and compare it with the fresh installation that works. Done means identifying the cause and documenting the compatible version or configuration for SD 1.5 training.
