What happened?

I updated webui. Then for some reason webui stopped loading many scripts. Currently only these three are shown

Then I added a script for "dynamic prompts" and this one gives me an error.

Error loading script: dynamic_prompting.py
Traceback (most recent call last):
  File "~~~/stable-diffusion-webui/modules/scripts.py", line 168, in load_scripts
    exec(compiled, module.__dict__)
  File "~~~/stable-diffusion-webui/scripts/dynamic_prompting.py", line 52, in <module>
    class WildcardManager:
  File "~~~/stable-diffusion-webui/scripts/dynamic_prompting.py", line 65, in WildcardManager
    def get_files(self, relative:bool=False) -> list[Path]:
TypeError: 'type' object is not subscriptable

Steps to reproduce the problem

1. Go to ....
2. Press ....
3. ...

What should have happened?

All scripts will be loaded.

the list[Path] error implies you're on an old version of python prior to [3.6?] with the old type specification conventions.

Please confirm your current python version and upgrade to 3.11 if needed.

Just a heads up - updating to Python 3.11 will require torch 1.13.0, which might be responsible for #3878
