Optimum

hey there! i’m totally stuck with this one. like so many others, i easily managed to own the user but can’t figure out how to escalate privs. the problem is i can’t even confirm if i’m on the right track since my meterpreter sessions always dies when running local exploits. i gave the exploit suggester a shot but the session dies before it finishes, so i’m basically down to trial and error. can someone gimme a hint on how to get my session stable? i’m aware of the x64 arch and stuck to x64 payloads and exploits, but to no avail.
