Images overflowing creating a horizontal scroll bar

I'm sorry Leo,
I think I finally understand what you're saying.
Eliminate the wordpress block cover all together.
Use a generate block container and add a background image to that container.
Make page full width as you described.

I've tried it and it works pretty well

Glad to hear!

Yeah cover block is unnecessary if you can use the container block from GB :)

Thank You for your help and patience LEO!

No problem :)
