Infinite black screen after starting a sale in MC

Hi I'm trying to make a sale on MC but everytime I try to start a sale the game just gives me a infinite black screen of loading.. I remember this happening back on Ps4 and I tought it would be fix by now.. But apparantly it isnt. Is there a way to work around it? Can I wait for it to start the sale mission or do I need to restart the game for it and lose part of the product im saling? This is like the 3rd time Im trying to make this sale and it just keeps on giving me the black screen..

PS: Im using the avenger and my personal car to stop the game from giving me the post mail.
