Modemmanager Segmentation Fault

Hi everyone!

I'm trying to connect a 5G interface and having some issues..
During the analysis, after sending dmesg command I've got the following output:

Is this a segmentation fault? Can anyone explain how to debug it?

Thank you!

Do you see any entries in logread at those time points?

Yes, I think that is this:
