ESP Now sender, this is the first time I’ve gotten here. There is no ammonia, no LPG.

I’ve just started getting this same error backtraced to the same module and function. I’ve been able to build and upload the part of the project that has that dependency on its own and the I2C works fine, but when it’s included with the rest of the project that is using wifi.h and some other libraries I get this error. Have you made any headway with this?

so just after doing some sniffing around it may be that its something to do with using I2C and SPI at the same time on the ESP32.
Ok problem solved. After using some super fancy print line debugging it turns out it just didn’t like the lostPower() function from the Adafruit RTClib library. Which was working fine on its own, but was just throwing that Guru error. I just removed it since it wasn’t adding much with the battery backup to the RTC module that will last 8 years or so and things are working fine now.

Without being able to articulate it, this is what I thought was going on, tripping up the guru by creating pauses with confusion.
