Katalon will not load known_hosts on windows

I’m trying to get Katalon Studio to link to our CodeCloud instance and I’m failing. The first issue is I have a known_hosts file on Windows but when I try to use Window>Katalon Studio Preferences>General>Network Connections>SSH2>Key Management>Load Existing Key, it fails to load. There is no error description or anything to go on. Permissions look good. I’m trying to set up a new SSH key to link to the repository but can’t get past this step. Any suggestions would be appreciated.
