So they pushed a new version to GitHub late september:
This should be the maintained version ahead of what they offer as a download on the official website.
Common other issues:
- When reinstalling, make sure to first remove all old files:
sudo rm –rf /var/db/receipts/*CH34xVCPDriver*.*
sudo rm -rf /Library/Extensions/CH34xVCPDriver.kext
also don't forget to check for any related files in
/dev/ and the .app file in your applications folder if these already exist.
Restart the device before reinstalling.
Restart the device after installation.
Try a different USB-Cable / USB-Hub.

Update February 2022: Now with Monterey out of closed Beta this works like a charm for me. At least for the Web IDE.
