Unable to Open a Project

Hi, I created a 16-minute video on Premiere Rush in Windows 10 and although I’ve worked on it over several weeks and exported it previously, I now can’t enter the project from the home screen (when I click on the project the screen goes gray and then comes back to the home screen). I have other projects and I can enter and edit those without issues. I really need to make a few changes to this particular video for an important project and export. Does anyone know why this would be happening and what I can do to rectify the issue? As a last resort, is there a way I can extract the latest edited version of the sequence from somewhere so that I can work on it elsewhere? TIA (BTW I have checked and all apps are up-to-date and my PC specs meet requirements – and as I said above, other projects still work fine. I’ve also restarted my PC several times, fully logged out of Adobe apps and logged back in)
