Issue to starting a conference

I recently downloaded and updated the new version of jitsi for docker.

I would greatly appreciate your help and sorry for the inconvenience.

Starting the conference gives me an error and says:

Unfortunately, something went wrong

The error in console is:

react_devtools_backend.js: 2273 2020-07-26T23: 32: 37.728Z [JitsiMeetJS.js] <Object.getGlobalOnErrorHandler>: UnhandledError: null Script: null Line: null Column: null StackTrace: Error: Focus error, retry after 1000

I followed these steps:
Download and extract the latest release
-Alternatively, to test the latest changes clone the repository: git clone && cd docker-jitsi-meet
-Create a .env file by copying and adjusting env.example
-cp env.example .env
-Set strong passwords in the security section options of .env file by running the following bash script
-Create required CONFIG directories
-mkdir -p ~/.jitsi-meet-cfg/{web/letsencrypt,transcripts,prosody/config,prosody/prosody-plugins-custom,jicofo,jvb,jigasi,jibri}
-Run docker-compose up -d
