It is happenning to me also.
Send the file thru backburner on another physical location thru vpn; and connect remotely thru anydesk to see the progress and It gets stuck on parsing scene, almost forever if you don't do any click on the screen, anywhere you want.
When it finish the job, and starts another one, an unkown error on backburner appears and the task won't start rendering and I have to restart the pc so it can start rendering again. This happens over and over again.
Using 3dsmax 2022.2 and corona 7 hotfix 1.
