I'm using the Yandex browser and I have the same problem. The versions 220.127.116.112 and 18.104.22.1689 are affected. After a downgrade to version 22.214.171.1248 Auto-Fill works fine again. Please fix this as soon as possible. Without Auto-Fill the app is useless to me. I'm using Android 10 on a Samsung Galaxy S10e.
