No file found to render template with handle "full"

Permalink
Hi,
I updated to 8.5.4 from 8.5.1 and not whenever I try to change themes, I get an:

Unexpected Error
No file found to render template with handle "full"

I checked and the full.php template is available and the permissions to the file and directory are 755. I also tried changing to 777. If I go into the themes area in settings, I can update the theme and I don't get any errors. But if I try to change the page theme, then the error shows up.

Do you have a 'full.php' file in your theme?

you probably dont have a 'default.php' page type in your theme.

Sorry I should have posted that I got this fixed. I applied upgrade again and then it went away.
Thanks for the help
