How can I run FiveM via sandboxie?

I’m trying to run FiveM with sandboxie but the process just doesn’t open. What can I do?

Have you tried using the -cl2 flag?

Yeah, I just tried it but it didn’t work. I’m not trying to run 2 FiveM instances at the same time tho, I want to run 1, in sandboxie.

It opens saying checking files and then it closes and never opens again.
