Altium Designer Crashes whenever I open PCB Document

Hello,

If you got an Access violation message on Altium, and closing and reopening the program doesn't work, the best way to deal with this type of problems is reinstalling Altium. Please try that and let us know if you are still having the problem.

Let me know if you have any questions!
Thanks,
Elizabeth

Hello there,

It seems like your Altium registry has been corrupted. Have you tried restarting your Altium software? If that did not work, please uninstall your Altium software completely then have a clean installation of it.

Let me know if it worked on your end.
