kodi 18? if yes, you need v0.6.6 (with script.module.iapc v0.2.1) if no, please include the version of python interpreter (iirc the walrus operator requires python v3.8). (easiest way is always to install the repo and then install from it).

It's Kodi matrix with Python 3.7.3 (default, Jan 22 2021, 20:04:44) [GCC 8.3.0] on linux

alright that means I need to upgrade to Python 3.8 to get it running? Thanks for the info :)
