This error may be due to different reasons, such as an outdated app or a poor network connection. But, if you are facing an error with your Vizio Smartcast smart TV apps disappearing or not working, there are several ways on how you can solve the issue.

First off theres no yellow button on my remote, as for an app manager, ya hes also nowhere to be found. My best guess is there both watching tv on an LG or Samsung.
I just went to settings; admin & privacy; reboot tv and my apps worked
What Angel did worked for me
I think my Vizio TV might be out of date, it is only like a year old but but it has no yellow button. It does not have settings in the menu, the apps are at the top of the page and it just shows them, there is no way to delete them or reinstall them, nothing. Also, I have my computer, laptop, phone, Roku all on my 5g network, this Vizio only sees the 2G, it does not even see the 5G. Maybe I have to have the better network for some apps? I can reboot the TV with the menu, set up the internet connection, and look for updates, or reset the TV, that is about it.
What Angel suggested worked for me to at least be abl yo art cast again. The apps still won’t show up on the TV didplay.
