I can play on multiplayer worlds created by my friends but friends cannot join my multiplayer worlds

Hello, this is my first ever bug that I have encountered whilst playing Minecraft so I am quite surprised to say the least

Before reading - please note that I have definitely got all of the correct multiplayer settings enabled - I triple checked this before making this bug report

Recently, before the latest update, Minecraft started having this intermittent issue where it would crash my game out of nowhere whilst playing with friends and then for a few hours, no matter what I tried to do in my world's or PC's settings, my friends would not be able to join back on my world via invite or manual joining (I would not show up as online on my friends' screens, despite being connected to the internet on my end, also whenever I tried inviting them to my world by pressing the invite to game button in the in-game menu, the invites would not send)

The issue used to go away after a few hours but now it has come back permanently

I have tried restarting my PC, updating my drivers, closing and re-opening Minecraft fully and in different ways (for example, from my PC's task manager etcetera), disconnecting from and reconnecting to the internet, I even tried disabling and re-enabling my network adapter device and I looked in the firewall which says Minecraft is an allowed app/it isn't blocked, basically nothing has worked so far

I am still able to join any multiplayer world despite having this issue, so I know that the problem is definitely on my end

I would really appreciate some help and advice regarding this situation, many thanks in advance for your time
