Can't get the lid to budge. Anyone else have a similar situation perhaps have a solution we haven't tried. We are renting and really don't want to destroy pan if we don't have to, although drilling ahole in lid may be final option.
Right now I have it in the freezer so the food doesn't rot.

You could try using a plastic spatula or other plastic utensil that could be wedged between the lid and the pan.

You may have to pour water into the pan. If water can leak under the lid, it will help to break the vacuum seal. Try twisting the lid left and right in order to allow the water to get in.

You can also try pouring dishsoap around the rim of the glass lid and twisting the lid back and forth.

Another possibility might be holding the cover and try twisting the knob counter clockwise to see if it can be loosened.
