Watson doesn't start on Win10 + Python 3.9 x64

[julhe]

I installed watson via pip3 install td-watson
However, uppon start with watson start TestProject I get this:

Traceback (most recent call last):
  File "c:\users\julian\appdata\local\programs\python\python39\lib\runpy.py", line 197, in _run_module_as_main

    idx = bisect.bisect_right(fullmoons, now)
TypeError: '<' not supported between instances of 'method' and 'int' 

Happens with both Powershell and Git Bash.
Note that this also happens if I just do watson, so it seems not related to any argument. I did a reinstall of Python + restart, but that didnt help.

Any Ideas? Feels like I'm missing something important...

This is an issue due to the latest arrow release. It has been fixed in #408 but not released yet!

Closing as duplicate of #410
