Error: SPI bus already initialized.

When trying to use this code on the esp32c3 mini chip, the version number used was esp-id5.0,f and the corresponding interface was modified.

What SPI1_HOST bus id is? it looks like spi_flash already initialised that bus. Can you check if lora attached onto the same bus? If yes, then you don't need to call spi_bus_initialize.
