It seems the modem disappears abruptly as per the following log: <<<<<< type = "New MT Message Indicator" (0x10) <<<<<< length = 1 <<<<<< value = 00 <<<<<< translated = [ report = 'no' ] [2101]: <debug> [1656296202.119915] [modem0/ttyUSB0/qcdm] unexpected port hangup!

One unrelated comment: please don't use an online paste service to add references to log files, it's better to attach the logs to the email, so that they are kept as reference for the future; your logs expire in 7 days since you posted them.
