I currently switch between Go, Rust, Python, Java and Kotlin pretty regularly. One minor thing that helped a lot was to have custom IDE settings for each (different code fonts, different background colours, etc.). I found it helped get into the mindset of a language a bit quicker by having them differentiated (e.g. I can switch to window and know what language I'm dealing with without having to read any code).
