Just "mount /dev/nvme0n1p3 /my_mountpoint" should work. If it can not be mounted, then your filesystem is corrupt. Exfat is not well to fix with linux, you should do it in windows. I suggest, not to use an installed windows, as windows (boah, crap!) will automatically want to mount any newly seen partition, which is bad for fixing using chkdsk. So my suggestion, use a rescue-windows, must not be based on Win10, even an old WinXP lifefile will work for that. The other way is, to boot an installed windows into rescue-mode and then you can fix the drive with chkdsk, too.
