Content Egg Pro cannot be installed because of an error !

Hi there, after the latest update the plugin was disabled because of an error during processing. I get this message “Requires extension mbstring. Content Egg Pro cannot be installed!”. This problem was caused after I updated the PHP to version 7.4. So I checked the PHP settings and found that by default the “mbstring” function is unchecked. So I checked it and everything started working again.
