Outer Glass on Oven Door shattered - OK to use?

I am finding it hard to find a replacement for the outer glass panel on my oven door (that exploded/shattered yesterday). Even AppliancePartsPros.com says that the part is no longer available. Does anyone know where I can get this (or the door) replaced?

Also, while we wait for the part, or to purchase a new oven, is the oven still safe to use? The smaller inner glass window is still in place and the door seems to be insulated. We do not have small children. Can we still use our oven for awhile (several months)?

Hi.

I was not able to find any information on the glass. It’s not available.
Regarding using the oven without it - it’s very dangerous. The inner glass gets very hot and incidental touch may end up with burns.
Also the t* balance wont be normal.
