Windows 10: Why does my backslash not work?

All other keys work perfectly fine, but when I type with my backslash, it gives random characters from the 3rd row of a keyboard. KASDFHL\;'456GJ. It also applies CAPS LOCK. If wondering, I use a GMMK keyboard and have reset my settings several times for it.

Backslash button not working and typing backslash after the letters a and s continously

The following are my recent observations from today:

1) My backslash button doesn’t work but after typing the letters "a" and "s", it types backslash sign continuously till backspace or any other key is pressed.

2) Also, I have noticed that if I press and hold the backslash key and then type the letters "a" and "s" then it types "a" and "s" only and not backslash signs continuously as it does when I just type "a" and "s".

I have checked the keyboard's driver, it's up to date and working fine. The sticky keys, toggle keys and mouse keys are all unticked. Also, I have restarted, shut down the computer multiple times. However, still the problem continues.

I have to either press backspace every time I type "a" and "s" OR else press and hold the backslash key first and then type "a" or "s" to get only "a" or "s".
Every time I type only "a" and "s", it looks as follows:

1) a\\\\\\\\\\\\\\\\\\\\

2) s\\\\\\\\\\\\\\\\\\\\\\\\

3) My backs\la\s\h button does\nt work but a\\\\\fter.

Please help me to resolve this issue. I have checked the help and support section of Microsoft but there is no such exact issue mentioned there and thus unable to fix it.

typing backslash

Backslash is there on the 8 key, I believe you click & hold ctrl key the 8 key to type backslash.
