I just typed a whole guide on how I managed to solve this in detail and the tab got closed out... in short then, download
Qualcomm drivers and not oneplus's. There are many drivers in the file, just extract the whole thing and point to the file on device manager and include subfolders. It should find which I think was the HS-USB QDloader 9008 driver then install. Make sure you download the correct MSM for your version. The latest for global (or O2) is only hosted on one server and was going to take 12 hours to download on highspeed internet so I used lemonadep_22_O.05_210324 being 11.2.2.2. Use the Win7 version. Even though you cannot use EDL, you can reference these
key combinations to get it recognized. If you're having a completely black screen, use the all button press hold until it vibrates. Make sure you are shutdown all the way and if needed use fastboot to. With MSM opened, drivers installed, and phone off, hold both vol keys and connect to PC. Hit Enum to refresh connections and hopefully it shows up and you can get a successful download complete. I found that the black screen was actually the device being in recovery mode. It was possible to successfully enter recovery using boot with power and volume down at times, although all sideload OTA's (along with prior fastboot flash boot *.img, fastboot -w, fastboot update, fastboot reboot-edl, ect.) failed. There was a lot of trial and error where just repeating some things after they had failed almost magically started working or stopped however this process is what worked in my case.
