Sorry, I can't reproduce your problem on my MySQL-instance 8.0.17 with JDBC driver version "mysql-connector-java-8.0.15". I can only reproduce it when the SQuirreL's MySQL-Plugin is not installed. You may look at menu Plugins --> Summary to check if the MySqlPlugin is installed. If not you may reinstall SQuirreL and during the installation choose to install the Plugin. You can find the latest installer versions here: https://sourceforge.net/projects/squirrel-sql/files/3-snapshots/snapshot-20260531_2129/...
