Hey besartdion,
Thanks for letting us know the steps you've already tried with this situation. There are a couple other steps worth checking as well just based on what you're describing.
I'd start by closing any background applications before launching Apex, especially those with overlays like Game Bar, Overwolf, Discord, etc., hardware monitoring tools, RGB software, antivirus/security software, or other programs that hook into games.
If you're not sure what other programs or processes might be affecting this, try a clean boot to temporarily disable everything but the system essentials to see if there's any improvement.
This is one of the most common causes for what you've mentioned, especially if you're not seeing any error messages and just get returned to desktop directly. If you're seeing an error message after this, please let us know the full text so we can take a look, thanks!
