Stress and problem (Patreon)

And so, this is the situation. I filmed the video on GoPro and got very hot, it didn't bother me much until I noticed that the battery was swollen. I tried to pull it out and it so happened that the battery before had damaged the memory card, which I could not pull out at first. I pulled out the 256GB card, now it does not work. Now the question is how to pull out the battery? I watched the video in which the GoPro 8 was disassembled and the battery cannot be removed there. Maybe someone can give advice, or someone got into a similar situation (on other GoPros). Because there is no money to buy a new camera, but you need to shoot a lot.
