ASRock B650M Pro RS and 8500G only recognize 1 DDR5 RAM.

My CPU is AMD Ryzen 5 8500G.
My ASRock B650M Pro RS motherboard BIOS is 3.10.

I put the TeamGroup T-FORCE VULCAN Z DDR5 RAM 32GB (2x16GB) 5200MHz at the DIMM slots:
A2
B2

I have only one TEAMGROUP MP44L 1 TB M.2-2280 PCIe 4.0 X4 NVME SSD.
I put it at the gen 5 SSD socket (M2_1) but it prevents the POST screen from appearing, i.e. only a blank screen appear, so I remove it for now.
Then I get the POST screen.

However, ASRock B650M Pro RS and 8500G only recognize one DDR5 RAM at the A2 slot but its speed is at 4800Mhz, not 5200MHz.
The other three slots are "Not Present".
What do I do now?
Do I remove and reinsert the DDR5 RAM at the B2 slot until it is recognized during POST?
Do I put the gen 4 SSD on a gen 5 SSD socket (M2_1) only after both DDR5 RAMs are recognized during POST ?

The POST screen appeared 10-15 seconds after the computer is turned on.
Then it stayed the same (was unchanged) after a long time (more than 30 minutes).
Is there a way to change the "RAM training" time?
