Hmm strange, this chart shows US consulate in Islamabad is 0trying to clear up the backlog aggressively for F21: The Islamabad consulate's C21/F21 visa issuance rate (Spouse of lawful permanent resident) (visawhen.com)
Anyone on this thread got F2A or F2B categories approval recently? This site shows the embassy has stopped issuing visas after beginning of 2019.

Looks like Islamabad embassy has not issued even a single visa since March 2019. Not sure when are they going to resume visas in this category
