I have un-installed KStars and INDI, along with removing any references to the package/repo. Deleted the .indi and KStars directories to remove any configuration files and databases that I am aware of. Re-ininstalled following the directions in
indilib.org/download/fedora.html for Fedora 31.
Everything left at default settings except for geographical location. Defined a local simulator profile with just indi_simulator_telescope and indi_simulator_cdd.
I still get the same result KStars log attached. Both the telescope and ccd simulator drivers fail just depends which one fails first.
Running indiserver directly does not provide more information.

I tried usig gdb variations but will spare you the details since none were successful.
I had previously (Dec 30) fetched the sources to try and debug why the scope did not always park when the roof closed. If I rebuild just the telescope and ccd simulator driver executables using those sources then they work with the rest of the install.
Looking at the original executable compared to the locally built one with debug info things look normal.

I am hoping an update will show up that fixes this issue. Otherwise I will remove indi kstars from the update cycle and do local builds to get going again.
