Well when trying to install the latest APK (don’t have fdroid) I just get a message that it didn’t install because my system is not supported?

Thanks for the tip. Newest version doesn’t run on graphene though. Second newest does.

I had a similar issue on an HP Elitedesk 800 mini G3. It turned out to be a faulty ram stick. Memtest revealed the issue and after unpligging the defective stick the issue was resolved.
