I have a 2016 15inch Macbook Pro. Im running Big Sur 11.5.2 and Lightroom Classic 10.4 whenever I export images it will shut down my entire computer. I have over 100gb of memory free so its not like its full.
Ive turned off the graphics card which is what I've read online and tried a million other things. Nothing seems to work.
Shut down the entire computer — this is almost always caused a hardware malfunction or caused by a bad/corrupted/out-of-date driver. In the case of exporting images, it may be that the computer is overheating, and this happens because a fan or part of the cooling system has stopped working; and also can be made worse by having computer case vents that are blocked by dust or other objects.
