Cannot really connect to the Realm after the 1.16.4 latest release on Java version

Since yesterday's update that I could not connect the realm anymore, it stopped at "Connecting to the Realm...", I tried to re-installation of the game and restart the system as well, but nothing was changed, continuously, continuously showing "Connecting to the Realm..." . plus, due to this new version update the game crash became a little bit more often.
