I get this:
"VEML6075 Simple Test
Failed to communicate with VEML6075 sensor, check wiring?"

See below 2 images from my oscilloscope. They show SDA (yellow) and SCL (Blue).
First with Adafruit solution:

Second with the working library from GitHub:

You better get a Nano 33 BLE and tryout yourself. Thank you in advance.

we dont have a nano 33 BLE to test with. however, if you dont see the i2c address during a scan, then something else is wrong and its hardware related not software, because i2c scanning is just a hardware test.
what is the text output from i2c scanning?

our best recommendation for now is to use the other library!
