TeamViewer Panel - minimized Teamviewer.exe - Application Error

Hi, I am getting the error below when restarting my machine remotely with an active TeamViewer connection. The teamviewer session closes but the machine will not restart due to the error.

If I schedule a restart for shortly after I close the connection, the machine restarts as expected. Issue occurs on both versions 12 & 13, I haven't gone back any further than that.

HP XW6200
