Computer won't boot after CPU upgrade

I'm at a loss. I recently purchased a new CPU during black Friday. After swapping it in, the computer won't boot. The fans spin up for several seconds, then it just restarts. The CPU and DRAM red lights are solid while it's on. I don't have a speaker, so no beeps. When swapping the old CPU back in, it works fine. BIOS is up to date, motherboard supports the CPU, and I've tried resetting the CMOS. All I did when swapping back and forth was remove GPU and swap CPU.
Motherboard is an Asrock X570 Phantom Gaming 4 (BIOS 4.3), old CPU is a 2700X, and the new CPU is a 5700X. PSU is evga, I think 600 watt. GPU is 5700XT.
Is there anything I'm missing?

No, it's on the most recent firmware, and the website lists it as compatible with the CPU.
No, I wasn't. I also used the jumper to reset the CMOS just in case there was a setting conflicting. This is the RAM I have: Corsair CMK16GX4M2Z2933C16 VENGEANCE LPX 16GB (2 x 8GB) DDR4 2933 (PC4-23400) C16 1.35V
I tried removing one of the sticks as I saw that worked for someone, but no dice. They're in the recommended slots per the motherboard manual and they've worked fine with my 2700X. I guess it's possible they're not compatible with the 5700X, but I'd think they would be based on what I can find.
I checked the 5700X for bent pins but they all looked good and it slips into the slot easily both times I installed it.
1. Did you try leaving the system to cycle a bit when you installed the new CPU? Sometimes Ryzen wants a bunch of time to re-do memory timings, etc.
2. Did you really update to the 4.3 bios? Looking at your motherboard site (https://www.asrock.com/mb/AMD/X570 phantom Gaming 4/index.asp#BIOS) it looks like there are a lot of warnings about how you have to use a Zen3 (Matisse) CPU or newer to update. Under the 3.20 BIOS update is a link to instructions for using an older CPU (you have to create an EFI-bootable USB, and use the command line).
1.) I did leave it for a little while, but I don't think it was actually POSTing, just stuck in a boot cycle. I never saw the GPU fans spin up when it was cycling like that and nothing ever displayed on the monitor.
2.) I think so? It was a while back, but I just downloaded the file (X570PG44.30) and flashed it through the BIOS like normal. The BIOS shows the version as P4.30. I guess it's possible I didn't do something correctly. I'll look into it.
Edit: And I see that 4.3 isn't the most recent. I thought it was but I was just looking at the CPU compatibility list. I could try 4.50.
What version were you on before? You could go back to that and try again, or try re-flashing with 4.3 using the instructions here:

EDIT: I think you will need to put the 4.3 bios file in the BIOS update package directory (take out the old BIOS), and then use the command prompt instructions.
EDIT 2: Have you tried contacting Asrock for guidance?
Hmm, that's very possible. I haven't contacted ASRock yet because I figured it was probably something simple I was missing. I'll research more into updating the BIOS. That at least gives me something to pursue. Thank you everyone for the suggestions!
