Connection 'GSM connection 1' deactivated: Is this a known issue with the device?

The modem on my Librem 5 appears to keep disconnecting:

Is this a known error with the device? I plan to switch OSes to see if this is the issue later today but wanted to first report it here in an attempt to make developers aware of the issue and see if it can be resolved.

Modem (cdc-wdm0) This device could not be configured

No.

Is this a Mobian-specific error? If so, I can report it to the proper maintainers through the official channels.

I just want to make sure it is not device specific, as this may require I contact the Purism team for hardware support.

I would not know the answer to that question.

I have decided to change carriers from AT&T to Mint and see if perhaps this is the underlining issue.

If anyone else has experience with Mobian on the Librem 5, please do let me know!
Mobian also recently released a new version—I shall attempt this as well.

I have experience with Mobian on the Librem 5, but not with weekly builds nor alternative desktop environments.
