Since installing this update, It hangs on "Creating a new file..." , I have tried uninstalling and reinstalling, but it doesn't work. (Steam - Nightly Build)
Does opting out from the nightly builds helps? What OS are you using? We've re-checked in our test windows system and everything seems to be working fine in the latest nightly build. Have you checked steps in the docs? https://ar14.works/docs/troubleshooting
