I set up DAKboard to autostart when I boot my raspberry pi 4 running bookworm. Every time I boot into the kiosk mode, I get a "Desktop Manager Is Not Active" error.

Any ideas on what I need to change so I can stop the error and exit kiosk mode into the desktop GUI?
A lot has changed in the 10 years since the thread you cite was published. In particular RasPiOS Bookworm has brought a lot of significant change to the way the Desktop GUI is managed.
The forums are fortunate to have a volunteer who has written up Guides on related topics.
Have a read of Running A Program At Start Up A Beginner's Guide. Covers multiple methods and troubleshooting.
