Remove it before it'll make more damage to your laptop.

You cannot fix it - only replace. If laptop is still on warranty - RMA it. If not - search for battery replacement somewhere on eBay.

Hello. Does anyone know how dangerous this is? How can I fix it? Please note that there are no Razer stores in my country nor resellers.

It’s dangerous using electric device that has swollen battery inside, for the parts inside and you as well since it might be a fire hazard. Remove it and get battery replacement for your model on market place like Amazon or eBay, anyway assuming from port it’s older blade stealth like from 2018 or earlier I don’t think Razer has still stock of it. You can still use it on ac adapter power without battery attached, using it so my break the motherboard, once the motherboard broken it will be a lot expensive.
