You should install older version (20.04)

Do you guys know when the fix will be available for 22.04? No sim error is a pain...

Sadly, it will never be available.
Reasons are discussed here.
I doubt Fibocom has ever released a firmware with mbim interface. But this is truly a good read to learn what the problem truy is.
