I’ve used the oven method for two different gloves, but used shaving cream on the first one and a specific treatment foam on the second one. It’s been 10 years since I last played, but I remember putting it on a cookie sheet and we turned the oven off before placing the glove in.

Sucks this happened to ya. Hopefully somebody around you has a spare you can borrow until you can figure out a replacement and get it broken in.
