Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

I receive a terminal error when trying to use specific upscalers. This is specifically through the Extra tab, I have not tried hires fix. I have no issues running 4x Ultrasharp, 4x NMKD, etc, however I cannot seem to run upscalers such as https://civitai.com/models/142699/8xnmkd-faces160000g-upscaler, https://civitai.com/models/292030/8xnmkd-superscale150000g?modelVersionId=328284 or https://civitai.com/models/318385/4xrealisticrescaler100000g?modelVersionId=357054

Steps to reproduce the problem

Copy any of the following to ESRGAN and try to upscale via Extra tab
https://civitai.com/models/142699/8xnmkd-faces160000g-upscaler, https://civitai.com/models/292030/8xnmkd-superscale150000g?modelVersionId=328284 or https://civitai.com/models/318385/4xrealisticrescaler100000g?modelVersionId=357054

What should have happened?

Uspcale normally without error

Same issue here, but with 4xUltrasharp_4xUltrasharpV10.pt
My install is managed by StabilityMatrix, hence the odd paths.

i can't seem to upscale anything 2048 x 2, it says 100% done but remains stuck still using 11.8 gb vram, did full reinstall still happening.
