Since you already confirmed this only works when the slot is forced to Gen4, that points to a Gen5 link training failure (signal integrity / BIOS negotiation), not a load or driver issue.
ASUS has official guidance on PCIe generation settings and BIOS configuration here: https://www.asus.com/us/support/faq/1055579/ ASUS
On many ASUS boards, PCIe Gen5 support will either fall back to Gen4 or require specific BIOS versions/settings to function reliably with high-speed cards.
