Hi ho! Thx! Here's how to report bugs in Houdini!

I could not reproduce the issue so it might be a preference issue. it might help pressing the teddy bear icon closing houdini and restarting again. This is very much a shot in the dark though. And yes a bug and an example file would help a lot.

There's no character at all in your hip file? But even without a character, I'm still able to enter its viewport state without errors in 21.0.671.
