I have always broken in my gloves with oil and practice. I decided to hurry this one along by using the suggested oven tip I have heard about in the past. “Oh, just put your glove in the oven!” I never believed them, because I feared it would catch fire. I thought I was wrong. My Easter was ruined today.

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.
Shaving cream then crank oven to 400, turn off and glove in is how I did all mine as a youth
