What do you think the shield is blocking? My intention is to permanently
mount this shield and resume using the oven.

Rather repair/have repaired the leakage. Check that the magnetron is
properly mounted. However, if you measure the leakage to be in
"normal" acceptable range and it can't be easily reduced more, then
the controller circuitry might just be too sensitive. Then you can use
the shielding, but make sure it won't cause shorts!
