npm run build also just works fine.

Hey @hellow554, we are looking into yarn@2+ issues and work-in-progress #35194 might also solve this issue.

Just out of curiosity - are you using PnP mode of yarn@3? or the node_modules / node_linker mode? (not sure if it's relevant, so far I was debugging issue with yarn@3 PnP, but the issue might very well be just yarn@3 regardless of mode)

Just out of curiosity - are you using PnP mode of yarn@3? or the node_modules / node_linker mode?

I'm using the default and IIRC it's using the pnp mode.
Not an expert though.
