Hey there Jose!
My name is Miguel Ángel and I'm an independent advisor, also a Microsoft user just like you! I'll try to help you today with your issue.
In order to solve the issue that you're experiencing, we should take as reference this website: https://redragonshop.com/pages/faqs#:~:text=How.... That contains all the frequently asked questions, so it's helpful.
In that link, it says: "Is it able to restore keyboard without software?
Use combo key with pressing Fn key + PRTSC (right next to F12 key) for RGB backlit keyboards, as for Rainbow backlit keyboard, press Fn key + ESC key still for about 3 seconds and then press F1, F3 and F5". Please, follow those instructions from the manufacturer and see if it helps, as this is mainly a Windows forum and our knowledge about Redragon and its keyboards is very limited.
I'll wait for your reply! Don't worry, everything will be okay :)
