If it helps, I can reliably crash this everytime with the following three steps, using the out-of-the-box A Warm Welcome setup:
Press A (to get page 2/2)
Press B+C (to get Snapshots menu)
Press C
This hangs the UI with purple centre LED.
Confirmed that this particular repro is fixed with Release 1.12.1 (21 Dec 2022), but might be unrelated to @LorisDonatelli original issue.
