Pretzel Rocks might not be opening or it opens offscreen/invisible
Did you recently unplug a monitor or change your display setup?
Pretzel Rocks has a positioning issue we are investigating at the moment, however, there is a quick fix.
Windows
Press the Windows key + R and paste in %APPDATA%/PretzelDesktop in the run prompt. This will show you a Pretzel app directory, in which you should see a window-state.json file. Deleting this file will reset the window position for the Pretzel Rocks app. Restart the app, and it should work normally again.
Mac
From the Finder menu, click Go > Go To Folder and enter the path:
In this folder, you'll find a file called window-state.json. Deleting this file will reset the window position for the Pretzel Rocks app. Restart the app, and it should work normally again.
