slpkg problems out of the blue

Hello humans.

I've recently ran into problems while trying to use slpkg. It has worked for me previously which I think is weird, I've never had this problem before. I've tried reinstalling multiple python3 dependencies but nothing seem to work.

These are the errors I get:

root@slackware:/etc/slpkg# slpkg
Traceback (most recent call last):
File "/usr/sbin/slpkg", line 5, in <module>

locale.setlocale(locale.LC_ALL, '')
File "/usr/lib64/python3.9/locale.py", line 610, in setlocale
return _setlocale(category, locale)
locale.Error: unsupported locale setting

Has anyone experienced this before?
