I ask because V-Ray the past year or so, causes lots of funkiness in Slate if an IPR is running. It didn't use to but it has since Max 2023 and V-Ray 6. I used to be able to have really fluid interactions in Slate while IPR was running. Now it's really slow and I have to start and stop it often to get things working again. If you do have V-Ray, and you have been noticing the shortcut problems while and IPR render is running, try stopping that render and see if the shortcuts behave now.
And if this is the case, I'd suggest you head over to Chaos Group's forum and report it. I'd like to figure out why the IPR is not so fun anymore with Slate.
