Magic Keyboard with Touch ID and Numeric Keypad for Mac models with Apple silicon (USB–C) - US English - White Keys space bar not always responding when inputting text

I purchased the Magic Keyboard with Touch ID and Numeric Keypad for Mac models with Apple silicon (USB–C) - US English - White Keys from apple for my MINI MAC 2025. It was delivered on 5 February. Since then, the space bar does not always respond and therefore all of the text is run together. Happens when typing text into searching on the internet and when typing text in the PAGE application. What can I do other than sending it back for a replacement?
