Most of 3D Printers that came with SD Card (not Micro-SD one) got similar problem which is SD Card slot is very loose, and sometimes printer lost ability to read the data inside due the SD Card not contact properly and lead to failed print.
Print this and put it to your sd card and plugged into the slot. and it will help the sd card to stay contacted with the SD Card slot.
My Ender 3 V3 SE have this problem, also some of the Anycubic Vyper user has been reported that they also got this problem.
