Movies being shortened to less than runtime

I’m having an issue that is weird. Plex will start playing a movie or show the runtime and it is always less than what the content is. I go and check the content using a player in my computer and it will show the entire thing, but plex will stop and freeze up. Any ideas on what might be going on?

I haven’t seen / heard of that one before.
Would you mind sharing some more details e.g. on what platform you’re experiencing this (server platform/version, PMS version, client platform/version, Plex client version) and some details about the media (do you see this behavior with all items or only some, anything those files have in common…)?

On a windows pc (windows 10)and these files are on a different drive than some of my movie files. They are all more recent within the past couple of months but they play fine elsewhere.
