I have successfully been using XAMPP on my windows 10 PC to run a website that I am working on locally until today.

When I try to start MySQL, it fails. The error logs state:

mysqld.exe: Table '.\mysql\db' is marked as crashed and last (automatic?) repair failed
Fatal error: Can't open and lock privilege tables: Table '.\mysql\db' is marked as crashed and last (automatic?) repair failed

As I try to fix this, I attempted the following:

mysqlcheck --repair --use-frm --all-databases

but this gives me the following error:

Got error: 2002: Can't connect to MySQL server on 'localhost' (10061) when trying to connect

Which I guess makes sense because the mysql service isnt able to run.

I have also tried running the following from this directory: c:\xampp\mysql\data. Doing this results in an error saying 'db' doesnt exist.:

myisamchk -r db

I noticed that i have a db.MAD file that is rather large 174,616K, so not sure if that is the problem.
