This is not 3.10 specific but has existed since the stop+resume feature (which I love and need) was released. The temp directories in which the upscaling is processing does not remove itself upon completion of the scaling. I have run the tool as normal user and admin. I end up removing the directory (using WSL2 since Windows delete takes forever to processing this large of a fileset) which is fine but wanted to make sure I wasn't missing something obvious.
Thanks.
