I'm at my wit's end with this, the short of it was I was having a lot of issues with Premiere last year. I now have the following:
Intel i9 13900k
RTX 4090
64GB of DDR5 6000Mhz RAM
Editing drives are all Samsung 980 Pros
Premiere Pro is legit unusable for me, I open it and it constantly crashes, I've tried reinstalling Premiere, installing older version, clearing cache and all other settings. I've reinstalled video drivers and older video drivers, but at this point I'm at a loss. I can't get client work done so I've had to resort to installing Davinci Resolve to try and edit (Davinci seems sweet but I've always used Premiere and it's just so much more comfy for me).
I've looked all over the internet and I can't seem to find any help for this issue, so thought I'd create a post about it. I did notice today that I finally got some sort of error message when Premiere launches stating that my video driver (531.18) is unsupported but I had already tried installing older drivers and I'm experiencing the same issue.
I have tried other projects as well, but the issue seems to carry over pretty much no matter what.
