I have had a similar issue recently, after several system crashes (hard
resets), and possibly a mariadb update.
I start KMail. It said it couldn't start the Akonadi service. Clicking the
Start button again, it did nothing.
'akonadictl start' did nothing, no output at all.
'akonadictl start --verbose' indicated that it couldn't start the mysql server,
similarly to the original description of this bug report.
Attempting to start the mysql (mariadb) server manually, with the same
arguments that the Akonadi server uses, just said that it was starting the
server, then quit with exit code 1. Same if I added the --verbose flag. Still
no clue why.
Then it occurred to me to check the mysql log. It was this:

After some further googling, I resolved it by removing
~/.local/share/akonadi/db_data/ib_logfile* . Akonadi works fine now. I still
have no idea why this was needed, and why it works.
Akonadi should handle this scenario in a more user-friendly way.
