Problem with --tax-output=2021

[flanello]

Hello,
at first, thanks for the cool software.
Without the option --tax-output=2021 the program works fine.

However, when using the option --tax-output=2021 it prints the summary for 2021 on the command line but the csv file is not generated. It breaks with the following trace.

Traceback (most recent call last):
File "./tw-pnl.py", line 1124, in
