Hi @keithm34805399,
Sorry to hear about your experience. Before resetting the preferences, as suggested by @marliton, you may take a backup of your workspaces. Locations of the workspaces are as follows:
macOS:
- ~/Library/Preferences/Adobe Illustrator <version> Settings/en_GB/Workspaces
- ~/Library/Preferences/Adobe Illustrator <version> Settings/en_GB/Modified Workspaces
Windows 10:
- C:\Users\<your username>\AppData\Roaming\Adobe\Adobe Illustrator <version> Settings\en_US\x64\Workspaces
- C:\Users\<your username>\AppData\Roaming\Adobe\Adobe Illustrator <version> Settings\en_US\x64\Modified Workspaces
After taking the backup of workspaces, reset the preferences, and copy & paste your backup workspaces to the exact location.
Kindly update the discussion if you still need assistance with it. We'd be happy to help.
Thanks & Regards,
Anshul Saini
