[SOLVED] libreoffice-kf5 won't let save/export any document

[egc]

libreoffice-kf5 doesn't let save or export any document anymore. Libreoffice freezes/hangs on trying to save a document ...

In case anyone is running into this problem, the solution in my case was:
to delete the file lo_kde5filepickerrc.lock in ~/.config/lo_kde5filepickerrc.lock

I'm having this issue as well. Where is the file located? I can't seem to find it.
Thanks

As i wrote above: in my case it was in my home directory under
~/.config/lo_kde5filepickerrc.lock
or
/home/"username"/.config/lo_kde5filepickerrc.lock
