Fatal error PHP 8: TypeError: abs(): Argument #1 ($num) must be of type int|float, string given in abs() (line 138 of /var/www/html/web/core/includes/common.inc)

Ideally we have a test. Let's be pragmatic. Landing this.

Line 108 of ImageWidget needs to have the same fix applied.
$max_filesize = Bytes::toNumber($this->getSetting('max_filesize')) ?: $element['#upload_validators']['file_validate_size'][0];

Can we scaffold a test that opens all the widgets so we can verify this doesn't keep popping up?

While the patch above applies, seeing this error when trying

Symfony\Component\HttpKernel\Exception\BadRequestHttpException: Input value "edit" contains a non-scalar value.
