Problems uploading images to sites with Sonoma 14.4 Beta

Since going in the beta I have had problems uploading images to a WordPress site. This occurs with Safari and Chrome. There is no issue using my iPhone to upload to the same WordPress site and the support team at the hosting service have no issues uploading the same images I fail with using Windows systems. It is not consistent. The same file that has uploaded can later fail to upload after one or more files have failed to upload. Very small images (5-20k) usually upload but larger than that and I start to get fails. When uploading to a different WP site I get uploads succeeding but the images are corrupt. But here aI also gett no issues using my iPhone uploading to the same site.
