Apologies for not getting back to you.
I believe that the issues you (and others) may be facing are down to the version of python/wxwidgets etc. It is 100% something that we need to rectify, as we need to change across to the latest versions anyway. But as I’m sure you will understand, this can sometimes have a bit of a domino effect!
There are plans to also have a web-based version of the software in the future, so this would help aswell.
I can assure you that the Crumble along with the software aren’t dead, but with years of component supply troubles, our focusses have sadly been elsewhere (having to source alternative components etc).
It may be possible that there are workarounds, but unfortunately, as of yet, I don’t have an answer.
