No. Don’t do it.
You’re not experienced enough to install and maintain a Linux installation. Fuck those who says “Bite the bullet and just install Debian! It will never crash!” They won’t fix it for you when it does.
You don’t have anyone who’s supporting you physically. They are not a phone call away. They are ten forum replies away and won’t be there when you need them.
Windows 10 is no longer supported, but no one is forcing you to either uninstall or upgrade. You can keep running it if you don’t care about potential security problems.
Windows 11 is bad, but not as bad as you accidentally sudo removed /etc/fstab
in Debian. Between bad and unusable, ask yourself which one you want less. This is assuming you spent your whole life using Windows and less likely make major mistakes.
You can schedule your migration to Linux in the future though. Just build a second machine. You must have the money to build a second one. Don’t fuck with your production build.
They don’t tell you how much they are going to pay you, nor how long the contract would be.
