Error -Upgrading a Team Project

Using the Teams file. Everything was working fine and I was restarting the machine and then tried to reopen the Teams project then this error appeared. The project was created in Axure RP 8 and tried to open in RP8 only.
Updated MacOS and Axure RP8. Restarted machine several times but still facing this issue.

Hi @AbdulMuqeeth, would you be able to write in to about this error, and attach your file in the email so that we can help you troubleshoot this issue?

In the meantime, please try to recover a backup copy of your file by opening Axure RP and navigating to File > Recover File from Backup.
