After removing proxies while making space on my system I experienced my first system blue screen. I've been editing on this system for 2 years. Premiere locks up once in a while, but not like this.
Steps to reproduce.
Remove proxies from your hard disk from Project
Open Premiere, then open Project B for editing. Project B uses Project B proxies.
Open Project A while still in Premiere. Last saved version of Project A referenced proxies.
It happened 3x in a row. Gave some sort of video error. To solve, I recreated the proxies using Media Encoder. Then I was able to continue working. I would have expected Premiere just to notify me that proxies were missing. I also updated my video driver since the issue, so it could have been related to last year's drivers. Sorry I didn't pay better attention to the old driver version or bluescreen error - I had a deadline to meet and the bug report was an afterthough (though I did submit the crash report)
