Questions about F1 visa renewal at non-home country while current visa is still valid

[mh23]

title. I am graduating from Masters next month and waiting for my OPT. I have a job offer already. My F-1 visa expires in 6 months (November 2023). If I try to renew my F1 visa in June from Canada(non home country) and is rejected/refused for whatever reason, can I still re-enter US using the current F-1 visa? Or they will cancel that too? Pls advise. Thx
