I Have the same issue. On firefox gets a screenshot then blocks. On chrome just black screen
I had the same issue on Mac OSX Big Sur on Chrome, changing "@zxing/library" from "^0.18.3" to "^0.18.6" worked for me
"@zxing/browser": "^0.0.9",
"@zxing/library": "^0.18.6",
"@zxing/ngx-scanner": "^3.2.0"
I confirm that updating the library solved the issue mee too.
The documentation must be updated.
