pci express upstream switch code 12

Question

Motherboard b550 aura pro v2, CPU AMD r5 5600x, gpu RTX3060, RAM 16 (2-8), power supply 650 gold, sd m.2 240 kingston a 2000, hd 500, window 10. The problem is this. When working on the computer, a blue screen with the error whea.uncorrectable error flew out. After restarting the system, the error was repeated and the operating system stopped starting. I could not install it on an SSD because the device in the Windows installer stopped being determined, I eventually installed it on the HDD and an error appeared in the task manager PCI express upstream switch port code 12 device and 500-series chipset - switch upstream port, Id:pci\ven_1022&dev_43e9&subsys_02011b21&rev_00. In addition, windows 10 does not detect the network adapter and does not see the ssd. The most remarkable thing is that the Bios determines everything. Also on this Windows, the CPU, GPU, RAM in AIDA64 pass a crash test. I also installed the GPU in another system unit that works properly. Tell me the solution to this problem.

There was a problem with starting the PCI device\VEN_1022&DEV_43E9&SUBSYS_02011B21&REV_00\4&5f22ecf&1&020A.
