Matter integration doesn't work and I can't add Matter devices to home assistant

I’m very new to home assistant and smart home systems in general
, and I’m trying to get a better understanding of how everything works. This problem that i’ve recently came across, was when I wanted to configure my Matter wifi rgb bulb from Namron. I have previously connected this product and had it work before without much trouble. The first problem I had was with pairing the bulb again after I had removed it from home assistant. (I had to remove it first because of a connection error that I couldn’t fix) I scanned the qr code on the side dozens of times. It would recognize the bulb, but didn’t connect to it. The second problem happened after I tried to reinstall the Matter integration in home assistant, where I now don’t even have the option to add a Matter device in Devices and Services.

Thanks!

Please make sure you have the matter server add on installed.
