Serious error

Dear Adobe support

I have had serious trouble with my Premier Pro program. See attached screen shot describing serious error. Every time I run Premier Pro, this problem occurs after 10-20 minutes, and I have to restart the program. I av working on a Mac Book pro and have tried to upgrade the software. I am now running it on the latest Os Big Sur, but it does not help. I have also tried to reinstall Premier Pro, but the error still occurs. Please help me out.
