I had some trouble as well, have you tried restarting satisfactory? (Killing it in task manager, then re launching it through the epic launcher/shortcut)
If that doesn't work, maybe restarting the computer itself--something could be hung up.
All in all, my antivirus software was preventing it from running, if nothing else works then check that out.
Look in the virus chest, some antivirus softwares are picking up files from the game and classifying them as dangerous/viruses.
If that doesn't work, a more qualified individual will have to help.
Hope it works!
