I've tried restarting, I jack-in into project with shadow-cljs

OK, disabling Calva: Enable JSCompletions resolved it

Ah, then Calva should probably give some error message instead of silently just failing to do the job.

There wasn't anything in inspector console either.

It's an experimental feature that one could argue should be disabled by default, but it seems to mostly work and it really is valuable when it does. But some kind of hint when it causes problem would be polite, me thinks.

Guys, is there a way to sort ns requires and imports on file save? Like there are hooks in Emacs?

Not currently. There was a PR about that a while... @slack1038 might remember.

of course i do 😄 that is the PR for CLJ refactor support there i did added the feature for clean-ns the problem is only that cljs is not supported by clj-refactor

but maybe we could add this feature clean-ns without the other clj-refactor stuff dont know how logical this would be

I think it would make sense on its own, @slack1038. But not if it is Clojure only.

the clean-ns should work also for cljs
