Environment: Pi4B/4GB, 3.5" touchscreen TFT (http://www.lcdwiki.com/3.5inch_RPi_Display#Interface), Arducam IMX519 16MP camera.
My code used to work, but on a previous OS install. (erased the previous one accidentally while swapping cards around).
The desktop starts on the TFT properly. In the past I was able to use the QT preview without issue. However, now I get the following errors displayed after the various camera formats.
Any suggestions what I should try?
