In the picture it looks like the module 8822bu.ko was build ?? if you find the file you can try : sudo insmod path/to/module/8822bu.ko
or if the file is in the current directory then use : sudo insmod ./8820bu.ko just to see what happens.
Ok, so all sorted now, and for anyone else having issues with Realtek drivers for the RTL8812BU the RTL8812AU and the RTL8812CU, then please follow the instructions here, they work perfectly...
Unfortunately, it did not work for me on Raspberry Pi4 with kernel release 4.19.115-v7l+.
I bought a new USB3 WiFi adapter with the RTL8812BU chip.
I wrote to the support mail on the website you linked to.
Hope they can help
