Thank you (all), (if you have more ideas on commands, please let me know) i will keep your idea (nvme system drive removal) in mind and if nothing helps and no one have idea on commands to try (to shed some light on freezes) i will consider cloning system drive to a different drive with different size and reorganize drives in computer, but i will do it only if there is no other option/ideas about the freeze cause/commands.
Thank you in advance for command ideas/feedback.
