Logic Pro X problem

Helllo

I was working / mixing in a project in Logic Pro X and had a plugin window open ( Guitar rig 5 ) on an audio track. I pressed or clicked something, and the workspace dissaperared, only the plugin window was left open. I saved and restarted Logic, but in this project, only the plugin ( Guitar rig ) window openes, and workspace doesnt appera anymore. I tried opening saved backups but the same thing happenes every time. I cant even recover my tracks or anything. Is there a way to revert this error/ glitch, or even get my tracks so i can put them in a new project ?

Tnxxx alot in advance
