Great, good to know. My question is, can I take out the USB Drive that is plugged in right now that I tried these steps on? The solid green light is on, and I'm wondering if I can just pull it out without causing any damage to the motherboard.
Pretty sure a solid light means the procedure didn't start. The light should be OFF when it's done.
You can shutdown the system. It's fine. The BIOS flashback didn't work or should I say didn't start. Answer from Nemesia on forums.tomshardware.com

r/ASUS on Reddit: Flashback solid green light
December 9, 2020 -
Help me im about to smash this fucking motherboard to pieces its an ASUS x570 ROG STRIX F GAMING. Ive been trying for about 7 hours to flash my bios something ASUS claims take 5 mins using their flashback button. Well every single avenue ive tried I get 3 green flashes followed by a solid green light. Ive formatted my usb stick and set to FAT32. Ive tried windows and Bootice so far to no avail. Ive tried multiple USB sticks and it appears whatever has gone on my first USB stick I tried has been killed. Ive cleared the CMOS and tried again. Ive triple checked im downloading the right bios thats compatible with my motherboard after seeing someone else have this trouble. Ive tried with just the motherboard connected to the PSU, ive tried it as a full system with the new 5600x with the RAM and everything plugged in asif it was a working PC. Im at a complete loss, wait months for my new stuff to arrive for this shit to happen. Please please please can anyone offer any advice
