I have exactly this problem too but only since 14 August 22. It first occurred on restart from Windows 10 Update on installation of KB5016616, KB5012170, KB5015730 and Servicing Stack 10.0.19041.1852.
I assumed one of the above caused AI Suite 3 not to run, so I uninstalled the 2 that could be removed, KB5016616 & KB5012170 but Ai Suite 3 continued not to run with the 2 above warning boxes appearing each time it tries to be run.
I had a look at "Services" from "Task Manager" where one could see AI Suite 3 appears to run for a few seconds then stop.
I tried to re-install AI Suite 3 and failed. I tried to remove AI Suite 3 from "control panel - programs and features" and although the uninstaller appeared to run, AI Suite 3 did not un-install.
This morning I found this thread, which leaves me wondering why I didn't get this problem earlier. I have automatic updates set "on" in Kaspersky so if a database update causes this problem I should have seen it at much the same time as other posters to this thread. So perhaps others had the Windows Update described above some time before me and that update is a factor in the problem arising after a Kaspersky update?
I too am upset at the loss of Fan-Xpert cooling control, having all fans running flat out without need is just a waste of energy.
