After latest Migration LCD no longer works

[Phillip]

After updating/installing:
Arduino ESP32 Boards to v2.0.13 and
esp32 by Espressif Systems v3.0.4

I cannot get a simple 16x2 LCD to work as it once did.
The sketch is one I have used several times in the past.

Board used: ESP32-WROOM-32
I2C connections are: SDA->GPIO#21, SCL->GPIO#22

When power and GND leads are connected to the board it appears to be normally powered up.
However, when I connect #21 all is fine, but when I connect #22 the LCD goes dark.
Reversing the #21 and #22 sequence produces the same result.
If all leads are connected then power is provided to the USB cable the LCD flashes then goes dark.
I have tried other ESP32 boards of the same variety with the same exact result.

Any help will be greatly appreciated.

Thank you.

This is my exact hookup.

Thanks.
