Error: Could not open the mysql.plugin table. Please perform the MySQL upgrade procedure.
I recently installed Laragon and updated php to 7.VC15 x64 TS and updated MySQL to 8.0.18 winx64 However MySQL fails to start. The error log shows the following:

I thought that I should be able to easily switch between MySQL/MariaDB versions. Apparently I was wrong.
Any help will be greatly appreciated
@WideGlide : MySQL 8 data is not fully compatible with MySQL 5, so please run this command in Laragon's terminal to upgrade your data:
mysql_upgrade -u root -p

@leokhoa this happens even when you do a fresh installation. must be a bug..or laragon initialises it incorrectly
