Hardware accelerated transcoding is broken on devices with Celeron CPUs.

For now, fall back to 1.32.1.6999.

A beta release with a fix is expected on 19 June unless there are complications (see [this post](https://forums.plex.tv/t/1-32-2-7002/840714/117)).

To fall back to 6999, uninstall Plex Media Server. Use the “Uninstall Only” option (the first one).

Then install the SPK for 1.32.1.6999.
