I have the latest version of AL but my start screen seems to mixed with the project page... Ive restarted my computer, reset my preferences, & everything I could think of. Also, not letting me start a new project. An error does come on the screen, it just doesn't open. Pls help.
Sorry to hear about the trouble you are facing. I assume you are using the macOS v12.4 and Ai v26.3.1. If not, please update as these updates were released recently. If updating the OS & app doesn't help, please share the screenshot of the error coming on the screen.
Also, please check if turning off GPU performance from the Illusatrtor preferences helps or not.
Kindly update the discussion if you still need assistance with it. We'd be happy to help.
