One issue is that the cool XIAO round display needs a different set of libraries for each XIAO configuration. I've got to save my code files like this: "WorksWithXiaoSamd21andRoundDisplay20oct2026.ino", and it still might not compile correctly the next time I try because some library changed version.
You could try and create some wrapper library that figures out what's needed on the current platform and dynamically imports the correct libraries for it
