Can't select curve

Hi all. This is a silly question, but I can’t select the curve. When I click on the curve nothing happened but sometimes (rarely) select correctly.
Selection filer disable.
I’m using rhino 8 trial
curves.3dm (46.1 KB)

Hi -
Please run the Rhino SystemInfo command and copy-paste the result here.

Thanks.
When you click on a curve, is anything written to the command line? Does the content of the Properties panel change?
-wim

Hello- please update the gpu drives to the latest available on the NVidia website. Does that sort it out?

-Pascal

I’m having the same problem, i can select curves by making the square selection but not by cliking them, with polysurfaces happens something similar, i only can select them if the view is not wireframe, I have a mac M1

will leave here the SystemInfo results but it seems like a bug in Rhino:

Any better?
