Postman launches with a blank screen

I started facing this issue on updating to version - v8.2.3,

Try below approach, which worked for me..

Step 1: Add windows environment variable: POSTMAN_DISABLE_GPU, with the value: true

Step 2: From the same blank screen open a New Postman Window (File -> New Postman Window)

I had same problem on my linux machine. Simply run the following on your terminal until they both tell you no more process to kill.

killall Postman
killall _Postman

Expanding on the previous answer, I put a script together that performs the loop as many times as needed to get Postman working again:

#!/bin/bash

OUTPUT=$(killall Postman 2>&1)

while [ "$OUTPUT" != "Postman: no process found" ]; do
    OUTPUT=$(killall Postman 2>&1)
done

OUTPUT=$(killall _Postman 2>&1)

while [ "$OUTPUT" != "_Postman: no process found" ]; do
    OUTPUT=$(killall _Postman 2>&1)
done

Make sure you set the permission for the file correctly so you can execute it:

chmod 700 kill_all_postman_procs.sh

To run it:

./kill_all_postman_procs.sh or may you need to do sudo ./kill_all_postman_procs.sh

None of these worked for me, I had to go to "System Monitor" and kill a load of processes with names like "postman --no-sandbox", "postman --type=zygote".
