Worked for me, thanks to @EligibleHat48 update.

The fix is simple. No need to wait for MS to address this issue.
Double click both the Gaminput services and look at their location (“path to executable” it is called). You will see that one is located in your C:\Program Files (x86)\ folder, and the other is located in C:\Windows\System32 folder. With your explorer app of preference open both folders, find the executable (GameInputSvc.exe) and hover over it with your mouse. In a second a window will appear. Look at the creation date of the executable. I’m almost 100% certain that the one located in your Program Files (x86) is the the old one (creation date around beginning 2023)
Then check your installed apps (start > settings > apps > installed apps). You will see Microsoft Game Input listed there. The date is somewhere around Feb/March 2023, so this one is old.
Click uninstall !
Then you will see that the executable in the Program Files (x86) is removed. If there are leftovers just manually remove them (delete the complete Microsoft Gameinput folder - you will probably get a warning so you must delete this as administrator)
Restart your PC, check services and only 1 Gameinput will be listed there. If the service is not started, double click it, set it on automatic start, and finally start the service.
The event viewer will no longer display the warnings.
