Hello @Anonymous
I wanted to check if you were able to move on working on this issue. To fully understand your situation and to provide steps that help you, further information is needed.
If you found a solution on your side, please share it here in the forum. It will help customers who face the same issue. Otherwise it looks like your drawing itself was corrupt, so that it also would not open by AutoCAD Desktop Application caused by general file corruption.
Sending this file to my in a private message would also be one way to go in order to help you.
Best regards,
Thomas
