Cannot open UiPath Assistant nor am I able to sign in through Studio

Running UiPath version 22.4.3

I am unable to open UiPath assistant on an unattended robot account. The application will not start (both via shortcut and the root application), and no error message is generated. I have confirmed through task manager that Assistant is not already running in the background. It simply refuses to start.

Additionally, while attempting to sign in on UiPath using the unattended robot account I am encountering the error message “Cannot sign in or sign out while processes are running”. I have confirmed on Orchestrator that there no processes running, however this message continuously pops up.

I think somehow the two issues are related, however I have been unable to find a solution. Any help would be much appreciated.
