I recently had an issue that caused similar issues. Ended up being a bad wheel on the Z axis. Wheel was damaged and the carriage would move up and down as the Z axis traversed causing that stripped pattern.
Good luck!

There’s a podcast (Sad Oligarch) that outlines a lot of these “mysterious” deaths in Russia.
