Manually deleting the folder is more of the last resort type. I would first try doing it through the built in option.
Either through the web page
Either through the web page
/admin/purgecaches.phpOr the CLI
php moodle/admin/cli/purge_caches.php

I tried the solution from here: https://coderwall.com/p/py-nba/moodle-easy-solution-to-failed-to-unserialise-data-from-file-either-failed-to-read-or-failed-to-write
When I run php /moodle/admin/cli/purge_caches.php from my xampp console, I get the exact same "failed to unserialize" message in the console that shows up in a browser.
And when I look in moodledata/cache, it's empty.
Even .../admin/purgedata.php gets the error:

Issue resolved. As it happens, I had 2 folders that were labeled moodledata. I had cleared the cache in the wrong folder.
