The print does not resume and I am forced to stop the print. I am using an MK3S+, with no changes to the extruder. Firmware is 3.14.1

I tried different gcodes, even the ones that had come with the printer, it seems to happen randomly, some prints get it and some not. But it does not seem to be a gcode issue because even the pre-packaged prints get it. I also tried running the whole calibration again to be sure, but nothing seems to have been fixed.

Any ideas? Thanks in advance.
