I have a prefab with some text in it that now works thanks to @marcel 
fix.
When I look in the editor, the text does not cast a shadow but in the build, it does. If I add an image to the prefab, the image does not cast a shadow in the editor but it too casts a shadow in the build.
Is there a way to disable this?

add canvas data and disable ‘cast shadows’ - but you instantiate objects at runtime right?
yes

but there is a canvas in the prefab so i should be able to disable in the prefab?

Try - im not sure if the setting is applied currently when you add/remove objects to the canvas at runtime tho
I will try… I keep getting this though and it’s five minute re-import every time… i think it happens whenever i change my prefab … it looks like it think i also changed this prefab

I am going to create a copy of that prefab outside of the package cache to see if it helps

OK… can confo9irm that it works even in a prefab

I’m not changing/adding objects to the canvas at runtime though… i am adding the whole canvas with the prefab

Ok - and that works as expected?
Which Unity version and SRP are you on? I believe this is a known issue in earlier 2021.3 versions where URP tries to upgrade materials in immutable packages (URP bug). I thought it’s fixed by now
2021.3.3f1 with URP

copying to a non immutable prefix seems to have done the trick

I should probably update to the latest 2021.3 version
by user 563549194137239552
Yes please do, that’s an early 2021.3 and those were … problematic
I updated to 2021.3.17f1 and now everything is purple so now I get your Twitter joke

Reimportal all did the trick to fix it
