Roku player crashes excessively

Roku TV player crashes excessively during video playback. The crashes are completely random and cause the player to halt playback and call the Roku Menu.

I am having a similar issue. When I attempt to play anything on Roku, the app tries to load the media but crashes and returns to the Roku menu. I’ve checked that remote access is available and working on the server, and I’ve tried to play on the same network, with the same results. No updates are available from either Plex or Roku. Rebooting the server and the TV didn’t make a difference. Any suggestions?
