maybe i was too early with trying the LibreELEC repro... today i see that there is a new version 18.104.22.168.116...
and it is also comming with automatic add-on update.
but as you mentioned... the version 22.214.171.124.116 seems to have the same issue as in the previous version from LE repro.
EDIT: by using the working add-on from the zip file, i have two of my games those cause Kodi (LibreELEC 9.0.1) to crash.
Discworld 1 (german) and Monkey Island 3 (german).
Discworld 2 (german) and Monkey Island 1 & 2 (german) are working.
diskworld 1 is crashing immediately when starting the game,
monkey island 3 is crashing after the menu / logo (just after the monkeys fall silent).
in both cases there is no log from that happening after kodi started.
