I can’t delete my trash

I need help. I'm desperate. The thing is that a few weeks ago I downloaded an older version of Mac OS on my MacBook Pro just to create a bootable USB for a topic that is irrelevant. The thing is that I wanted to delete the download afterwards and it told me that the resource was busy. I renamed the file to any name (file that is inside a folder) and I did manage to delete it and put it in the trash. The problem I have now is that when I go to empty the trash it tells me that it cannot delete the file or the folder. I have tried everything and I am almost desperate because the hero in question weighs more than 7 GB that I cannot delete in any way. I have tried booting in safe mode but nothing at all. Please can someone help me remove it?
