thank you so much.
What do you mean? Is it something wrong with your keyboard or device? Personally it sounds like a virus to me.
What wallet are you using? I have experienced something like that they first time I used and exchange wallet. It didn't let me change my transaction address. I found out my internet server was glitching and the exchange was also having troubles. But afterwards I switched to another wallet. If you don't have any funds in this wallet, switch to a trustworthy wallet like Electrum.
Maybe, try and find tools in your wallet and click to get a new address. The wallet should generate for you a new and available Bitcoin address. You can transact Bitcoin to this address and it will end up in your wallet.
