Message app keeps crashing

[Tim98TA]

Whenever I go to delete a text, or a group of texts, the app crashes and wants me to send a crash report, which I do.
This is the message app that came with the phone. HTC One.
Has anybody else seen this? Is there a fix?

Try going to Settings>Apps>All​, select Messaging, and Clear Cache. If that doesn't help, and if there aren't any texts that you need to keep on the phone, Clear Data as well.

There shows 60.00kb of cache. When I press Clear Cache, nothing at all happens.
