Hello!
I've already searched and found out similar problems like that in the past, but the solutions were probably outdated, so the problem is that Quick Reply is Posting but you could only see the Posted Reply after Manual Refresh (The loading icon keeps loading...)

After Disabling plugins, Quick Reply works normally so It has to do something with them
This is the Console log output:

caught SyntaxError: Unexpected end of JSON input
    at JSON.parse (<anonymous>)
    at Object.quickReplyDone (thread.js?ver=1827:359:19)
    at Object.complete (thread.js?ver=1827:345:14)
    at c (jquery.js?ver=1823:2:28294)
    at Object.fireWith (jquery.js?ver=1823:2:29039)
    at l (jquery.js?ver=1823:2:79928)
    at XMLHttpRequest.<anonymous> (jquery.js?ver=1823:2:82254)

Any help would be much appreciated (I suck and should learn more JS/AJAX in future - will do)

activate one plugin after the other and check each time if the problem occurs
As soon as the problem occurs, you have the culprit and we can see further. I guess you are using PHP 8.x?
Which MyBB version do you run?

the more info you give, the more likely others can help you

Thank you for your response!
The culprit is indeed as I suspected the MyReactions plugin which is a shame

PHP Version is 8.1
MyBB Version 1.8.34

It is probably getting a PHP warning which is breaking the quick reply.
