The event does work, but the approach to removing a class from an element is incorrect. Instead of removeAttribute, you could use element.classList.remove(className) to remove the class.
removeAttribute
element.classList.remove(className)
const NEWSTYLE = document.querySelector(".movemaus");
NEWSTYLE.addEventListener('mouseleave', function() {
NEWSTYLE.classList.remove("try");
}, false);
NEWSTYLE.addEventListener('mouseleave', function() {
console.log("The Function is work in the Console");
}, false);
.try {
padding: 3em;
background: #B51C35;
text-align: center;
}
.try a {
display: inline-block;
padding: 0 .5em;
font-size: 2em;
font-weight: 900;
color: #FFFCED;
text-decoration: none;
border: 5px solid #FFFCED;
}

Hello Nisarg, Thanks alot for the great support and the quick response. I'm a beginner in JavaScript and I try not to understand it good, to avoid the copy Paste from another developer. Thanks again, wish you a nice day. Mustafa

removeAttribute removes the named attribute. The value you pass it should be an attribute name (like "class") and not a CSS selector (like .try).
removeAttribute
"class"
.try
If you want to remove a class from the element, then you should use the classList object.
classList
NEWSTYLE.classList.remove("try");
Dear Quentin, Many thanks to wonderful explain. Wish you a nice day. Mustafa

.try is a css class, not an attribute. You could remove the class attribute completely with removeAttribute, but not a single class out of the value. For this task you could use classList.
.try
class
removeAttribute
classList
And why not combine the event listeners?!
document.querySelector(".movemaus").addEventListener('mouseleave', e => {
e.target.classList.remove("try");
console.log("The Function is work in the Console");
});
.try {
padding: 3em;
background: #B51C35;
text-align: center;
}
.try a {
display: inline-block;
padding: 0 .5em;
font-size: 2em;
font-weight: 900;
color: #FFFCED;
text-decoration: none;
border: 5px solid #FFFCED;
}

SO is for both, beginner and pros. But to be honest, you should not use comments for ask things like this. Use meta.stackoverflow.com for such questions.

removeAttributedoes what the name says, it removes actual attributes from elements. There is no attribute named.tryon any element. If you want to remove this single class from an element … then go do some research, please, how that is done properly.– CBroe
