Mint is a great choice, it is very stable, and it really holds your hand via the Software Center.

However, stable also means old: it does not support the latest hardware.

If you have hardware that released after (rough estimate) April 2024, consider something based on Fedora, such as Bazzite, instead. It comes with modern drivers and should support modern hardware much better.

I heard it can completely crash your system if your a noob.

You can crash anything if you try. Been there, done that.
Just go ahead and start using it. Just keep backups which you always do, regardless the O/S and situation.
(pro tip: TEST RESTORING THE BACKUPS)

Maybe make an extra backup before you try something and you'll live. You could also use a separate partition to store your files so you can re-install without touching your data. Make that partition size 'recognizable' (t.ex. the biggest by far and label it) so you won't mess up the partition selection when you re-install. And NO don't ask me how I know!

Yes Mint is a good choice for your migration. It has been put together in a way that makes it intuitive for a windows refugee. The menu layout has the "start" (mint) button bottom left with your apps in there.

The system apps are named obvious things like "software manager" and it has default apps installed to get you going.

Being derived from Ubuntu it is the best supported platform for commercial apps/games but with Ubuntu's weird choices (snap etc) tidied up.

It's the most recommended linux distro for beginners for a reason. It's a solid reliable well thought out platform

I tried it a couple of times and stopped both times because it puts it own password dialogue box up for my password. I assume it wants to sudo for some reason.

No! I will not give you my plaintext password.

1. No other piece of screen sharing software needs this.
2. You've not told me what you need it for.
3. Even if valid, no user level software should have my plaintext password. Make a request to the system, it will prompt me.
4. You now expect me to trust the software developers that make such brain-dead security choices with sharing my desktop? Not going to happen.

Uninstalled as fast as I possibly could.
