Proton Error on Install first time

[muzzethesnd]

I Installed the ASA Manger like your guide and run the ./ark_instance*.sh after it downloaded everything sucessfully it errors the following lines.
After that it says "INITAL SETUP COMPLETED" if i use the number 2 (list instances) it shows "No Instances Found in '/home/*/ark/instances' Dunno whats going on here (Fresh install of everything dont change anything.)
Pls Help :D
[EDIT] My System is Ubuntu 20.04.6 LTS

Proton prefix initialized. Starting server once to generate configuration files... This will take 60 seconds Proton: Upgrading prefix from None to GE-Proton10-4 (/home/muzzeserver/server/ark/server-files/steamapps/compatdata/2430930/) Traceback (most recent call last): File "/home/muzzeserver/server/ark/GE-Proton10-4/proton", line 2055, in <module> import protonfixes File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/__init__.py", line 8, in <module> from . import fix File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/fix.py", line 12, in <module> from .util import ProtonVersion File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/util.py", line 25, in <module> from .config import config File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/config.py", line 40, in <module> config = Config(Path.home() / '.config/protonfixes/config.ini') File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/config_base.py", line 61, in __init__ self.init_sections() File "/home/muzzeserver/server/ark/GE-Proton10-4/protonfixes/config_base.py", line 86, in init_sections section_name = member_name.removesuffix('Section') AttributeError: 'str' object has no attribute 'removesuffix'

#24 -> on Ubuntu 20.X install python 3.9 then change the path on GE-Proton*/proton first line from python3 to python3.9 save.
Redo ark_instance manager with setup (1 on choice) -> fixed and done.
In Proton the subscript protonfixes need python 3.9 - import protonfixes only works with Python 3.9 .
Now everything is working. Thx to #24 for reference!
