Hi im doing a project in which i need to run 1 ICM20948 9dof imu sensor and 2 veml7700 lux sensors through the PCA9546 I2C multiplexer. Separately they work absolutely fine however when the 2 codes are combined the imu stops working. the lux sensors continue to give me accurate readings but the imu seems to stop giving accurate readings. does anyone have any experience with these sensors and multiplexers? many thanks.
Lots of people have experience with multiplexers.

Not sure I can help, I do not have the data sheets or your annotated schematic showing how all of this was wired, or powered.
I think you put your finger on it. When the 2 codes are combined, the problem appears. What does that tell you?
