Hey tansribossku,
I see that your GPU drivers are out of date, but if you're still able to play offline then that shouldn't be causing you to crash when you go online. I'd still recommend updating them just in case. You can find updated drivers here.
It's frustrating that you're not getting any errors, as that's making the troubleshooting somewhat harder. Especially because it's only crashing when you specifically go online, but you've already tried deleting squad files and repairing the game.
Could you try running a system file checker?
