What are you using to run the game on M1? Looks like it doesn't set up the java-objc-bridge library properly, you'll probably find that the in-game narrator option is broken too.

I'm using multiMC and https://github.com/yusefnapora/m1-multimc-hack to run minecraft.

It's an issue with m1-multimc-hack, see yusefnapora/m1-multimc-hack#32 (comment)
