I recently had Windows update (Windows 10 Home - Version 10.0.19041 Build 19041) and updated Premiere Pro to 14.7. Now, Premiere crashes nearly constantly. I can open a blank Premiere window (no project loaded, not even the startup screen), move the screen around and it will crash. Of course, if I load a project, it crashes randomly there too. It doesn't seem related to any particular action. It can be just sitting there and crash. I am using an nVidia GTX 750 Ti video card. I upgraded the driver to 460.89. That didn't help. I also reverted to Premiere 14.6, but have the same issue. Currently, Premiere Pro is useless. I'd really like to get it running again.
My system meets the spec requirements you listed. I have an nVidia GTX 750 Ti graphics card which is not listed in your recommended list, but does have 2 GB of VRAM and worked before. Everything else is met. As a side note, Photoshop also randomly crashes. Is there anyone to submit a crash report to? Initially, it did generate a crash report, but after the first crash when it did that, the window just disappears with no error notice.
But you have an unsupported video card, so it's not going to work reliably or not at all with the 750. The oldest cards they are currently supporting are the 900 series, yours is two generations earlier than that. Use an older version of PP or get a more modern GPU.
