Storyboard pro 7 crash after start in MacBook Pro

When ever I am opening my storyboard app and started working on previous file it’s crashing instantly. I was using windows system previously nut recently I shifted to MacBook Pro and started facing the problem.

I was facing the issue from the time when I updated my MacBook os to Big Sur 11.0.1 version.

It’s really frustrating.

Please let me know if any one have any solution.
