All HDHomerun recordings "interrupted" since 2/3 update

Since the 2/3 update, I've had a couple of problems that have made Channels completely unusable for me, and I'm hoping someone could point me in the right direction.

I have a HDHomerun Prime and a Quatro. Prior to the 2/3 update, they worked reasonably well. Season passes usually did the right thing, commercial skip usually did the right thing. But post-upgrade, literally every recording shows as "interrupted".

I don't record that much, and there haven't been any collisions as far as scheduling goes. This happens on cable and OTA recordings, so I can rule out too many tuners in use, or schedule overlaps.

This seems to go hand-in-hand with the Channels app causing a hard crash on my Nvidia Shield Pro (2019) which is only acting as a client. At best, I can get about five minutes (doesn't matter if the content is OTA, cable, or a DVR recording) before the application freezes and the Shield either reboots on its own, or needs to have the power disconnected to become responsive.

The Shield is stable with the HDHomerun client and DVR, as well as other vanilla apps (Netflix, HBO Max, etc.) I checked today to make sure I'm using the current version (as of 2/8/2022) of the client. But my guess from the wonky recordings is that my underlying problem is with the server itself.

I tried doing an in-place reinstall, but that didn't seem to help. The system that Channels is running on is dedicated to Channels DVR and Plex, so it definitely isn't a resource issue. Any suggestions?

How is the dvr connected to the network?

Are TVE, prime and OTA all affected?
