Error: MySQL shutdown unexpectedly.

I started having this problem when I installed Mamp for windows.

This is the error log

2017-08-25 20:18:12 14184 [ERROR] InnoDB: Attempted to open a previously opened tablespace. Previous tablespace gizmoelperro/wp_term_taxonomy uses space ID: 10 at filepath: .\gizmoelperro\wp_term_taxonomy.ibd.

InnoDB: Error: could not open single-table tablespace file .\mysql\gtid_slave_pos.ibd
InnoDB: We do not continue the crash recovery, because the table may become
InnoDB: corrupt if we cannot apply the log records in the InnoDB log to it.
InnoDB: To fix the problem and start mysqld:
InnoDB: 1) If there is a permission problem in the file and mysqld cannot
InnoDB: open the file, you should modify the permissions.
InnoDB: 2) If the table is not needed, or you can restore it from a backup,
InnoDB: then you can remove the .ibd file, and InnoDB will do a normal
InnoDB: crash recovery and ignore that table.
InnoDB: 3) If the file system or the disk is broken, and you cannot remove
InnoDB: the .ibd file, you can set innodb_force_recovery > 0 in my.cnf
InnoDB: and force InnoDB to continue crash recovery here.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware

You accidently joined the wrong forum, this is *NOT* the MAMP forum, but instead the XAMPP forum. XAMPP is another webserver distribution. You should move to a MAMP forum.
