Ivy Bridge & Big Sur & Clover -- Boot problem and others...

Hi!I upgraded from Catalina to Big Sur and the following issues occurred. Occasionally slow boot. Sometimes can't mount EFI. Sometimes there are no audio devices. (vga HDMI only). Sometimes Spotlight doesn't work.

System specs:ga-h61m-s2pv rev 2.0i5 35702* 8GB DDR3RX 580 4GBMacOS Big Sur 11.1 on SSD (MBR)Clover: 5128

Here is my config.plist

I uploaded pictures of the bugs, boot and the EFI.

Can anyone help me with what the solution is?
