A Pyrex pie plate or other Pyrex baking dish can go from the freezer to the oven but after you allow the Pyrex to warm up a bit to room temperature.
Don't immediately put the Pyrex Pie Plate into the oven after immediately removing it from the oven as it can break because of thermal shock.
Allow the Pyrex to sit out at room temperature for at least 20 minutes and then you can place the Pyrex Pie Plate or other Pyrex dish into the oven.
Pyrex is safe to go into a 450 F degree oven.
However you should not take a frozen cold Pyrex dish and then put it right into an oven or put a hot Pyrex dish from the oven into the freezer as it could break or shatter due to thermal shock.

Pyrex is very versatile and is made to withstand the temperatures of an oven.
Just don't put the hot Pyrex directly from hot to cold otherwise it could shatter.
But allowing the Pyrex to cool before refrigerating it or freezing it will prevent it from shattering.
But Pyrex is safe to use in the oven and can withstand temperatures of 932 F and any temperature after 932 F the Pyrex could shatter.
But ovens at home don't typically heat up to that temperature so you won't be getting the Pyrex hot enough for it to shatter.
