That's odd. I haven't had any other reports about errors on launch, and I just downloaded and checked the Itch and Mediafire links, which both ran without issue. Googling those errors points to a few results about corrupted files. If it was something corrupted going into the build, I'd expect to have run into this myself during testing, or have had a report from a tester or backer during the early access period. I'd recommend trying a new download and not installing any mods/tools (if you have). If that doesn't help, I primarily use Discord for bug/issue reporting, so if you have an account you're more than welcome to join the server and post the issue there for follow-up.
