I had the same issue, but was able to solve it by making sure signal had the "Local Network Access" permission on both devices.

Hijacking this thread to suggest that (instead of crashing) the transfer flow should remind you that this permission is needed on BOTH devices, since right now the process is not very clear.

Thanks, @0xjmux !
Independentaly from your comment, when re-reading the requirements I did turn on local network access and then the process worked flawlessly.
Maybe this issue should be about amending the wording of the warning, then.

Best,
Luca
