More generally, the issue happens with all exceptions raised by other threads.
Run the code below and interrupt with ctrl+c.
# If part of a file, potentially more code before the loop. Traceback says -1 regardless.

if not i%1000000:
pass # Or any other operation here that is faster than iterating a million i values.With the following traceback:
Traceback (most recent call last):

KeyboardInterrupt
The issue disappears as soon as we add just a bit more to the loop

The issue persists whether running from the shell or as a file or even using exec. It works the same inside functions/methods. It exists in 3.11 and 3.12 but not 3.10, across Windows and Linux.
