System drops to GRUB prompt after kernel update and release upgrade (UEFI, dual boot with Windows 10)

[andrew005star-debug]

System information
Initial Linux Mint version: 22.2 "Zara"
Updated Linux Mint version: 22.3 "Zena"
Kernel before update: 6.14.0-37
Kernel after update: 6.17.0-14
Firmware: UEFI
Boot setup: Dual boot (Linux Mint + Windows 10)
Update method: Update Manager (default settings)

Steps to reproduce

1. Install Linux Mint 22.2 "Zara" alongside Windows 10 (UEFI, dual boot).
2. Use Update Manager to install regular system updates.
3. Update includes a kernel upgrade (to 6.17.0-14) and system upgrade to Linux Mint 22.3.
4. Reboot the system.

Actual result
System fails to boot and drops to GRUB command line prompt:

GNU GRUB version 2.12
Minimal BASH-like line editing is supported.
grub>

System cannot boot without manual GRUB recovery.

Expected result
System should boot normally after a kernel update and release upgrade,
or provide automatic recovery / clear guidance,
especially on common UEFI dual-boot setups.

Impact
Critical. A regular update via Update Manager renders the system unbootable
on a common UEFI dual-boot configuration.
This is not recoverable by a non-technical user.

Additional notes
No custom bootloader configuration.
System was recovered manually after the failure.
