Where is OpenTabletDriver looking for .NET? Here's where mine is installed:

if you execute otd-daemon manually outside of the service do you get this issue?

Looks like it works fine if I execute otd-daemon manually! Go figure!

(Clicking on the otd-gui icon also does not work, yet if I start otd-gui by hand, it works just fine! Also, otd-gui throws this error: (OpenTabletDriver.UX:9055): GLib-CRITICAL **: 15:03:41.935: Source ID 35 was not found when attempting to remove it; should that worry me?)

should that worry me?
No

I would check your environment for why OTD isn't working with the service, I'm guessing your systemd environment (unrelated to running env) does not contain dotnet in its path. As for the desktop file, I'm guessing the same or similar thing, you can see the logs from it by running the desktop file in a terminal.

Looks like I had to add a line .NET to opentabletdriver.service, and that did it for the service. Can't imagine why clicking on the GUI icon doesn't work though, seeing as launching the desktop file via gtk-launch opentabletdriver.desktop works just fine!
