Kudos to Jim for identifying the cause by inspection, minimal example to reproduce:
PicoMiteVGA MMBasic Version 5.07.05RC3

> load "bug.bas"
> list
Option Break 4
On Key 3, break_interrupt
Do : Loop
Sub break_interrupt()
End
End Sub
> run "bug.bas"

Press CTRL-C

From TeraTerm: [Transfer->XMODEM->Send...] "non-trivial-file.bas"
The PicoMite{VGA} hangs and must be reset.
The fix within the program appears to be to clear the interrupt:
Sub break_interrupt()
On Key 3, 0
End
End Sub
On Key 3, 0
End
End Sub
It is not sufficient/necessary to restore OPTION BREAK.
Best wishes,
