As I've said, the 13" 2018 I use from time to time can easily manage a 32 buffer, even on Catalina, so your device should be just as good.. My suggestion is to try with a different adapter and maybe with a different DAW such as Reaper, just to double-check (although I don't really think the DAW is the issue here). It may also be related to the plugins you're using, maybe they're just heavier than mine..
