I can’t export my video yo my macbook pro anymore

Hello!

I have been using lightroom to edit the color of my video for like 3 years now, but lately i can't export video to my mac anymore!

first time that happened, my video did export but didn't appeared on my mac, i solved the problem (didnt have space on my cloud) everything was fine for like a month but now the video won't export at all! It says its exporting, but even after a whole day it still not exported!!

i cleaned up space on lightroom, on my mac, on my cloud everything!!! I tought it was the cloud the problem so i stopped the cloud in lightroom from syncing, but that didnt worked either. Please someone HELP ME!! This is my job and now i cant work!! I dont know what to do
