Not sure what initially caused your issue but try throwing a G92 E0 into your start gcode right after homing and also after any purge line you may have setup.
I’ve encountered this same error when trying to recover failed prints by restarting them at the failed layer. If you don’t tell the extruder it should already be some distance through the print, it throws out the exact same error. Since you’re starting at ‘0’ it needs to be told that.
