I have the exact same problem.
I'm running QGIS 3.4.5 with GRASS 7.6 on Ubuntu 16.04 Xenial (I have reinstalled QGIS from the ubuntugis-ltr repository today).
I also tried with QGIS 3.4.4 with GRASS 7.2 on a Debian strech.
I have no problem running GRASS in standalone but as soon as I try to run any GRASS algo from QGIS toolbox, I get this error: init() got an unexpected keyword argument 'encoding'
I have absolutely no idea how to solve this apart from maybe moving to Ubuntu 18 / Debian 10... or Windows...
Claas Leiner, have you solved your problem?

The problem persists.
My Workaroud:
Open the file
/usr/share/qgis/python/plugins/processing/algs/grass7/Grass7Utils.py
and delete every line with:
encoding="cp{}".format(Grass7Utils.getWindowsCodePage()) if isWindows() else None,
After that I can run Processing-Grass-Commands.
The problem does not seem to exist with all QGIS installation on Ubuntu. I use Ubuntu 16.04 and QGIS with unbuntugis dependencies.
