Android Question Rapid debugger failed to connect on every project

[Multiverse app]

B4A v 9.50
I've been suddenly experiencing stange errors on every project:


Presently I cannot debug any project. These projects work fine on release.
Any help will be appreciated.

Might be a problem with ADB. Try to kill ADB (Tools - Restart ADB server) and also test it with B4A-Bridge.

Restarting the computer might also help.

The issue persisted after restarts, but this solved it.
thanks.
