It's win 10 , Threadripper 3970x with 64 GB ram and a GTX 3090. I had the original version from a while back installed. I overwrote it that installation (or in this case unzipped to the same directory), and it started up fine and it asked to make a profile, but I declined just to try the game out quickly, then I played the first level and died rather quickly but it crashed. So I repeated it 2 more times and thought I might as well make a profile to see if it helped, and it didn't crash anymore. Though in hindsight, the old save file was there in the save directory so that could have been the cause of the crash. I just checked the save location and there are 2 files there now that were updated today, and on my backup from yesterday, there was just one file there from 2018.
