Pardon me for being so direct, but the main issue in your case is your own attitude towards Linux Mint confirmed by yourself in another thread:
In case you do not like Linux Mint, then this is ok, because it is your decision. In case you are not prepared to play Linux Mint in the way Linux Mint works, then this ok, because it is your decision to try and apply Windows rules to Linux Mint. But it will not work. Whenever you start playing a new game, you have to learn the rules, which apply to the game. If you do not wish to go through the learning curve, then this ok, because it is your decision.
Only do not put the blame for your decision on Linux Mint or on the forum users, who try to help you resolve the issues, which you report.
To be quite clear. We are not sitting in front of your machine. We cannot solve the problems, which you encounter. All we can do is helping you solve your problems yourself. The more precisely you desribe your issue, the more precise your questions are, the better and more helpful our answers will be.
Again understanding how to ask for help in an efficient way is a learning curve. A learning curve, which seems to exceed your patience.
As a consequence, I cannot recommend you any other Linux Mint forum. The more so as you ask for a forum supporting "Linux Mint 20.2 xfce". There will be no forum, which is specialized on one single Linux Mint release with one specific desktop environment. Would be a pretty short lived forum by the way, because end of April 2025 Linux Mint 20.2 xfce will reach the end of its supported life time.
You have joined the right forum for getting support on Linux Mint 20.2 xfce. But you may have to spend a thought or two on what you can expect in a users-help-users forum and what you cannot expect.
Best regards,
