Video channels missing after upgrade to v5.0.0

Hi there,
I trust you are well.

Opening a separate issue. I recently ran the upgrade to v5.0.0, but now the video channels are not displaying on the front end.

I find the following error in the log:

[15/Dec/2022:12:40:18 +0000] « GET /api/v1/accounts/noiz/video-channels?start=0&count=1000&sort=-updatedAt&withStats=true HTTP/2.0 » 400 375 « Noiz » « Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:107.0) Gecko/20100101 Firefox/107.0 »

The user profile pages also return a 400 error.

Any help would be greatly appreciated.
