Hey! After an update, you need to run uno clean from the terminal inside app folder. Also if you could share minimal reproduction code, it would be easier for us to help.
the first thing I’ve done is perform a uno clean… thats not the problem…
a minimal reproduction of code… that’s a problem… the error doesn’t say anything about where the error is… and thare is no “Uno.UX.Markup.CodeGeneration.UXProcessor” anyware in the code… so… I’m blind…
