I wanted to send this message to express how disappointed I am with the Premier Pro app and how frustrated I am with the crash error issues! I have been using this app for more than a year and though it has great potential it comes with problems like this! I worked many projects on the app and on every single one I had at least one crash error. I mean, okay, it is more than welcome to update with new tools the app and give us more and more, but lets face it everybody needs a smooth app to run. I always save data every 15 mins to make sure that I do not lose everything but that one time I won't it will certainly crash and make me lose what I had been working on for the last hours.
If you are using an Nvidia GPU, then there's a quick fix. Go to the Nvidia driver support page, download the Studio driver, and do a clean install. The more recent game-ready drivers have been causing all sorts of problems in Premiere recently.
