If you want truly water resistant, go with a Panasonic Toughbook. You're going to pay a premium and get a poorly-spec'd laptop, but they'll be obsolete LONG before they stop working.
Other odd thing with this Asus Zenbook: It won't read Samsung T7 external SSDs via USB-C but has no problem reading them over USB-A. Now, if I put a USB-C hub in the middle, it'll read them. Again, this is after doing a fresh reinstall of Windows.
