I’m on macOS 10.14 Mojave. I recently updated to Scrivener 3.1 Since then Scrivener crashes in the very moment when I try to open it. I’m no longer able to work w/ my data.
If you’re on the standard download version, then there is a fix, which is available on the website; https://www.literatureandlatte.com/scrivener/download. Just download and resin tall.
If you’re using the AppStore version, then the answer is the same! (Apple have a fix in their queue but haven’t released it yet, so download the website version as above temporarily and it will be accepted. When the App Store version has been released, you’ll be able to deinstall the temporary one and reinstall from the App Store.)
HTH.
