Sengoku Basara 3: multiple repeatable errors

The only relevant error there is

F {PPU[0x1000009] Thread (Resource Loader) [0x00fe4d60]} class std::runtime_error thrown: Memory mapping failed - blame Windows (addr=0xd02a0000, size=0x10000, flags=0x23)

Which means that it died with an allocation failure. Some memory sections in Windows cannot be allocated, this may be what's happening.
There's no real solution for this right now other than using a Linux or BSD distro.

Generally just ignore errors if you don't know what they mean and pay attention to the ones that contain user targeted messages (e.g. saying to read Quickstart Guide when Firmware is not present) and the Fatal Errors in Purple

You'll have to upload an actual log file for further help with the other issues, but they don't usually show up in the log. The game isn't Playable so what you described is expected behavior at this stage.
