Rhino 9 hangs when isolating objects, can take a minute or shorter or a bit longer , has nothing to do with the size of the file working with sometimes it hangs sometimes not can not pinpoint it why
or the size of the isolating objects does not matter a few lines hangs it
I’m afraid that’s not something that I’m seeing here. If you can find out what triggers it, please let us know. In the meanwhile, please run the Rhino SystemInfo command and copy-paste its output here so that we can at least make sure there are no simple suggestions to make.

I’ve experienced the same on my PC, I haven’t had the time to log this issue.
(Ryzen 3900X + 5070 Ti up-to-date Win11 and Rhino 9 build. Rhino 8 works fine.)
I’ve added an Alias (HH) to ! _Invert _Hide which is effectively isolating the selection, Rhino does not hang using this method.
