Our QA team observes the same bug - #7161
When we call Player.seekTo() method a video freezes and the player doesn't react to any media event. It's very hard to reproduce, on my devices it happens 1 time out of 1000.

We use the latest 2.17 version of the Player. There are no deprecated classes in our code. Timeouts are set by default.
It happens for any ads, even for ads from this list https://developers.google.com/interactive-media-ads/docs/sdks/html5/client-side/tags

Do you have any ideas about what can be a root cause? Any possible fix or workaround?
