Can't import collection from Insomnia

Hi, I'm trying to import my collection (100+ requests) from insomnia via json (I also tested via yaml) from the last version. But when I click import, the spinner spins forever and nothing happens. I read this thread: https://yaak.canny.io/feedback/p/import-not-working

And I tried with the beta but the same thing happens. I thought might be cause of the size of the collection so I tried with a way smaller one (less than 10 requests) and same behavior… help ^^

Thanks
