The only time I’ve resorted to the screwdriver technique (due to not having enough room to tighten and then turn a strap/chain wrench) the screwdriver shank just tore through the filter when I tried to turn it, a broader tool like a wide chisel might have a better chance of success.

What I ended up using that time was an air hammer with a broad headed chisel (pushing on the side where the impact would unscrew the filter). The angles wouldn’t work well for this in OPs case but if you have enough side access to get the air hammer through it’s a decent last resort.
