Hi,
the service was not restarting properly.
The logs as attached have only the basics and miss further info.

Currently is only contains that the service failed, but not why.
Usually the mysql error log holds useful information, but it wasn't attached on this report.

It would be very useful if you could attach that, so we can check what is failing on the mysql start.
