Hello,
I recently updated my Illustrator the the most recent version (24.2.1) and my tools are missing. I was able to reclaim the tools from the windows pannel but all of the options from the right side of the screen were still missing. Typicaly I would reset my workspace to "essentials classic" or "essentials" but I am currently stuck on my preset workspace and am unable to switch out of it.
A potential solution is installing a previous version to fix this issue, which has worked in the past for me. The intention with this post to to seek a potential solution and to notify the proper parties regarding this issue.
Hopefully this will be fixed in the next update. Thanks!
