2018.3.0b12 - collaborate stuck again on resolving packages

Hi. As usual, I've updated to new Unity beta. Then send my project updates to collaborate
Got back home. Tried to launch the project with beta12 on my laptop.
Started the usual conversion with local files by opening the project with beta 12 (before getting the update via collaborate) and with this beta version...Its stuck on resolving packages...
Checked all the firewall, tried with deactivating all of them. Not better.

Tried to directly take the whole project from a clean state. Not better. It gets back all the data until it tries to resolve packages. Or give a nice 'AN ERROR AS OCCURED' message on the collaborate window after starting to retrieve data.

All of that didn't happen since - i think beta 3 or 4 for 2018.3, something like that). And now It's back.
Any help?

You wanted a feedback about why 2018.3 felt not ready to get out of beta for me? Here's a pure example x3
