TotalSpaces2 not working on Sonoma

My computer was “fixed” by Apple, which installed Sonoma over my old Catalina. Now TotalSpaces2 will run, but cannot load a grid. My work has ground to a halt. I use 16 desktops at all times. It complains that it cannot manage the Dock, but I have allowed that, and it still cannot create a grid.

TotalSpaces2 will not run past Monterey if I recall.
TotalSpaces3 seems to work on Ventura onwards but is not as stable and the product is no longer receiving any updates.
