One of my Lovelace tabs not displaying after update

Configuration Frontend

After updating to 2021.4, one of my Lovelace dashboard tabs stopped working (it worked since 2019 versions up to 2021.3.x without issues). It shows nothing, just empty space.

Sometimes I see it for a second and then it disappears again so I think it’s some kind of web rendering issue.

Problem persists up to the latest, 2021.4.5.

I see nothing relevant in the log so far but I’m not sure. How would I go about troubleshooting this? Thanks.

Check for errors in the browser inspector.

Thanks, the inspector revealed a bunch of deprecated HACS cards. Apparently there was a breaking change in 2021.4 that broke some of the components, but it’s weird it took down the entire view. The rendering engine should be more fault-tolerant.
