Run Time error (invoke: no method named "loadAd" in class java.lang.Boolean)

Hello
I’m facing a problem every time I open the app it shows RunTime error (invoke: no method named “loadAd” in class java.lang.Boolean)
Also when I’m trying to adjust the blocks it shows errors and it development page of blocks lags
Please check the screenshots.
App: Screenshot_20220925-195602.jpg - Google Drive
Blocks:Untitledx.jpg - Google Drive

first fix all those errors

Do not repeat The Same blocks again and again. Instead use when any component event as well as use simple procedure

Thanks for your reply.
Actually when I delete these blocks they appear again once i refresh the page and the same error message shows again.
The app worked normally until the new update from Kodular, regarding changing the monetizing system.
