This error message could happen when you use two components, where component A is constructed based on the legacy i2c driver and component B is constructed based on the new i2c driver. In general, we don't expect the user to use both of them in the same application.

I am having the same problem but with 1 specific device model only, the ESP32-S#-LCD-EV2 board using the latest BSP for this device.

As far as I can recall the BSP (used to?) use some mechanism for auto detecting the I2C driver/module being used. Is it possible that both drivers somehow get linked in here?

Oh, I found it. I used an audio codec device. You need to close idf.Py menuconifg ->Component config ->Audio Code Device Configuration ->Enable backward compatibility for the I2c driver (force use of the old I2c_driver above v5.3)

Obviously a new setting, either related to latest master IDF or latest BSF.
Disabled same setting, boots now.
