Hello!
If you’re running Deadline 10.1.20.3 on Windows Server 2012R2 and go to open the Monitor you might be met with this:
To fix this delete the C:\Program Files\Thinkbox\Deadline10\bin\python3\Lib\site-packages\PyQt5\Qt5Bluetooth.dll file and re-try opening the Monitor.
Alternatively downgrade to Deadline 10.1.19 or upgrade Windows Server.
