Hello Steven,
Thank you for your message.
It seems like the issue might have been caused by some antivirus/firewall activity that could mistakenly damage or delete some files fr om the Host installation folder or Host's registry key.
Could you please try
fully uninstalling Host on the machine wh ere the issue occurs following
this guide, then restarting the remote machine and re-installing Host from scratch to see if this helps to resolve the issue?
In addition, please make sure to add the Host installation folder to the exception list of the antivirus software installed on this machine:
C:\Program Files (x86)\Remote Utilities - Host\.
Hope that helps.
