I'm sorry to hear about this. Do you also see this issue while adding media to a new project? Please let us know if you see this issue with a specific file type. Also, if you have any third-party plugins installed, please try temporarily disabling them (Here's how) and let us know if that helps.
Post moved to discussions for troubleshooting and collecting more details.
already had someone reset the whole creative suite with no help. I recently raised my Virtual Memory quite a bit and it seems to be working now. Still extreme high cpu and Mem use but manageable.
