Can you reproducibly get the crash at this particular UNBLOCK_INPUT?

If so, it narrows the problem to one of the functions called between the
BLOCK_INPUT at window.c:5484 and the UNBLOCK_INPUT at window.c:5720.

A possible way to debug this is be to insert code at intervals between
those two lines, to check the value of interrupt_input_blocked and abort
if it ever changes (which would indicate the existence of an extra
UNBLOCK_INPUT).
