Pause print - failure to restart print

Just put my MMU2S together a week or two ago and having a bunch of issues. But one that I can’t work around is that when I pause a print (to install a nut in a recess)  the resume print fails. Same manner each time. 
The extruder parks up for the pause then when I press resume print in the LCD menu it  moves over to the item being printed and lowers down till it touches the print surface then lifts off and goes back and parks itself again. Menu says Print Paused. 

Multiple attempts ( following on after first fail) gets same response. Same form of failure on completely different print.  Happens with both manual pause and with pause inserted in Prusaslicer. 

Any ideas?

Hello, same issue here MK3S/MMU2 with lattest firmware (3.8.1  /1.0.6) and latest prusa slicer (2.2.0)

Infinite loop after pause when printing from SD card.

And, when printing from octoprint, impossible to resume from the printer. So I resume from octoprint and, it starts, but with a cold extruder 🙁

Crashed 2 prints :/

Same problem here; I have only SD card print, not via RP PI Zero W. Can somebody help, please?

Same problem here, just if u do it <7 times to restart it finally restarts. (takes a long time and oozes filament on the print)

MMU2/ MK2,5s /prusaslicer 2.2.0

Hello,

It seams that this is corrected into the last 3.9.0 firmware :

https://github.com/prusa3d/Prusa-Firmware/releases/tag/v3.9.0

In bug section:

Infinite Loop

G-code M601 was in specific scenarios causing an endless loop.
