[Python] Python os.rename gives FileNotFoundError because of questionmark in dirname?

I'm working on a repo, where someone has named all directories with a "?" in the middle (home/runner/work/repo/repo/bla_123?-1_bla/file). This created all kinds of problems so I wrote a quick github action script that starts the following python script:

import os
import re
def changefilename():
dir_path = os.path.abspath(os.path.join(os.path.dirname(__file__), "..",".."))
for root, dirs, files in os.walk(dir_path):
for file in files:
root_split = root.split("/")
root_split[-1] = re.sub(r"([^\?]*)\?(.*)", r"\1\2", root_split[-1])
new_root = "/".join(root_split)
print(file, root, new_root) #for debugging
os.rename(os.path.join(root, file),os.path.join(new_root, file))

changefilename()


I know that the yml file is not the problem (I did something extremly similar but on a different repo and just copied from there). So the problem must be in the script or on the filenames. I get a FileNotFoundError on os.rename for a file adress where I know that it exists. (The print() command alone also works great and prints out the corrected root for all files in the repo, if os.rename() is removed.)

FileNotFoundError: [Errno 2] No such file or directory: 'home/runner/work/repo/repo/bla_123?-1_bla/file' -> 'home/runner/work/repo/repo/bla_123-1_bla/file'


My question therefor is whether the "?" might cause these issues and what i could do to work around that.

(PS: For context: The yml file contains runs-on: ubuntu-latest, which is why I used "/".join())
