crashing

My audition keeps crashing

Some files which are fine and have been working when opened just simply cvrash the program

My audition is a new install on a new machine and i used the old audition 2010 until recently when support stopped and never had an issue

This new audition has been 'buggy' since i installed it and keeps failing me.

what to do?

I even had a technician remote in and in the end we couldnt find the cause.

Do i reinstall and lose all of my settings or whatever? is there a way to back them up?

and how do i fix this?

clean reinstall?

this machine is fast and strong - 64g ram / NVIDIA RTX4060 / 3.64 TB /64 bit system / SSD drives /i7 core/ 8.19TB storage and NAS system -so why?
