Developer Rig (v 1.2.7) not work.
First, the program starts for a long time, after 1-2 minutes my extensions appear.
When trying to start any of them, it freezes again and after 2-3 minutes it tries to start but without success.
In the console I see a log “GET http://localhost:50170/coordinator.js net::ERR_EMPTY_RESPONSE”
I tried to reinstall the program, logged in again - it did not help.
