sysextd hang

Hi. My systemextensions hang when I do the system extensions list and I believe it has something to do with a hang when I tried to open system preference security and privacy.

BigSur 11.6.5

I disabled sip hoping that might help, os the state of sip is not relevant here.

How do I recover from it?

I already tried recovery mode and pram reset etc. And even I reinstall bigsur which doesn't help.

I am going to answer myself.

(re)install any network extension application will unblock the issue. I guess apple's network extension or system extension installation and update is not stalled in somewhere
