I have the same problem. With the card present, the code works very well. Without the card, the driver try to deinit SPI bus, but SDMMC was initied in SDMMC 4 bits mode, not SPI. My error is little different: |

esp32 module: WROOM
version: install latest 2.0.0
SDMMC begin and work succeed within case the SD-card have present in slot socket SD.
If the SD-card is removed out slot socket SD. Esp32 shall crash and reset log print as below.
with version: release v1.0.6
ESP32 example SD_MMC work normal with this case.
