Additional Information

i typed con in the wallet name

I tried to open a wallet file on a Cryptomator Vault (Windows).

Start with electrum/gui/qt/installwizard.py at on_filename and follow the call into electrum/daemon.py and electrum/util.py at standardize_path, where Python's Windows path handling raises the reported error. Reproduce the crash using the wallet name "con" on Windows and compare it with opening a wallet from a Cryptomator Vault. Done should mean the wallet flow no longer crashes, though the issue does not specify the intended handling for reserved or invalid paths.
