Temporary waterproofing of cavity next to window

[Gary111]

Hi, my cavity wall has moved out maybe an inch so the old architrave round the window doesn't cover the gap.
It's leaking in.
I need something I can put on when wet, maybe waterproof tape that will stick to the bricks as a temporary fix as the upvc trim supplier is closed today and tomorrow!

Thanks
