Same issue I am having, though I also have

  File "C:\Users\thisi\AppData\Local\Programs\Python\Python39\lib\encodings\cp1252.py", line 23, in decode
    return codecs.charmap_decode(input,self.errors,decoding_table)[0]

Right before the unicode decode error.

same...

   File "C:\Users\tregu\AppData\Local\Programs\Python\Python310\lib\encodings\cp1251.py", line 23, in decode
        return codecs.charmap_decode(input,self.errors,decoding_table)[0]
 UnicodeDecodeError: 'charmap' codec can't decode byte 0x98 in position 391: character maps to <undefined>

Here is my solution of "cp950" error for Windows 11 by changing system language:

Go to language & region setting
Select Beta version
Reboot your PC
Run webUI

It works for me. Maybe it works for other "cpxxx" error.

Hi there, my issue #297 seems have indirectly fixed, you can try it in my fork repo.
May try on my repo if it fixed.
So... won't need to change this operation system settings stuff

Hello, here is a fix suggested by Deepseek, which worked for me:

open ui_trt.py
Replace the line 269 :
with open(config_file, "r") as f:
By :
with open(config_file, "r", encoding="utf-8") as f:

This issue is addressed in PR #353 .
The fix enforces UTF-8 encoding when reading JSON files to avoid UnicodeDecodeError.
