instead of throwing, use std::error_code and such due to reasons unberknownst to me, the UID of the /tmp/eden directory was set for another user, this inevitably caused a crash due to wrong permissions (which is a very user unfriendly thing to do generally) Signed-off-by: lizzie <lizzie@eden-emu.dev> Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3912 Reviewed-by: crueter <crueter@eden-emu.dev>
