I'm also having this problem, started a couple of days ago, running the current (2/16/2021) version of Recursion and Windows, it was working fine one night, then the next day i started getting this error and haven't been able to fix it, Offline mode doesn't work, running the program in admin mode didn't work either, tried reinstalling, also didn't work. I'm not sure of what else to do to try and remedy the issue, any help would be appreciated.
