I have error from library when compile FeatureDemo projects in DOIT ESP32 V1 kit

Hello, I have compile the FeatureDemo projects of smartmatrix but I got some error like this:

How can i fix this?

It’s the same problem of this lib not being compatible with the newer esp32 libraries. I had to downgrade to an older version of the esp32 lib. @Louis knows about it, I think there is a bug open already, but don’t have it handy right now
