Sorry for my English. I'm writing through a translator. I have your LTE modem, the NB-IoT2. And it's been sitting idle for almost a year. I wanted to use the NB-IoT2 with a STAM PLC to control a relay. But YOU still don't have proper documentation. Or an example of how it works. Between the modem and the phone. Will the documentation ever be completed?

The "Failed authenticating" error is the key clue here.
Mifare 1KB cards use sector-based authentication with crypto keys. Bruce (and most generic RFID readers) will attempt the default keys (e.g. FF FF FF FF FF FF or A0 A1 A2 A3 A4 A5) to authenticate, but if FlipperZero or NFC Tools wrote data using custom or non-default keys, authentication will fail even though the UID and card type are read correctly.
Things to try:

Test with a blank/factory card. If it reads fine, your module is working.
Check what keys were used when writing via FlipperZero or NFC Tools and make sure Bruce is configured to use those same keys.
If the card was written with default keys, try a different card; it may have been locked or write-protected.

The fact that UID, ATQA, and SAK are being detected correctly strongly suggests the module is functional.

While investigating the sta.scan() crash, I discovered a second distinct firmware bug affecting the Tab5 in UIFlow2 v2.4.4.
Description:
On every cold boot, the device crashes during UIFlow2's initialization sequence before any user code runs. The device automatically reboots and boots successfully on the second attempt.
Crash signature:
Guru Meditation Error: Core 1 panic'ed (Instruction access fault). Exception was unhandled.
MEPC : 0x00000006
MCAUSE : 0x00000001
MTVAL : 0x00000006
Key observation:
The stack contains 0x7474696c (ASCII: "litt") pointing to a crash inside UIFlow2's LittlevGL/LVGL initialization sequence — not in user code.
Reproducibility:
100% reproducible on cold boot
Device always self-recovers on automatic reboot
Completely independent of user code — happens before any user application starts
This is a separate bug from issue #94 (sta.scan() at MEPC: 0x4ff13582). Both bugs share the same root environment (UIFlow2 v2.4.4 on Tab5) but occur at different stages and involve different subsystems.
