I have a big problem with my keyboard.

Hi, I recently bought the OldShool v2 RedSquare keyboard, and a big problem arose with it: after a while it starts to connect completely spontaneously, which is why the computer starts to hang and the keyboard does not work, the problem is in this series of keyboards, and not in computer, if someone faced this problem, help, I will be glad, the support could not help anything, they only insist on a quick fix, but so far nothing is happening.
