Could not build your widgets. This may be due to outdated widgets in your project. You can check which widget failed to build by clicking Project > Tools > Widgets.

Hi there, I did what the error message suggested but straight after that I get an 'Oops' error and an option to send feedback (which I did) Weird thing is, I tried removing all widgets and I get the same error in the project. It's in 7.19 and tried to upgrade to 7.20 but same error pops up. I also tried to update all widgets, no luck. I am running out of ideas, anyone experienced the same issue?
