Hmm, I did a search and it seems like Yandex browser is built based on Chromium, so I think it should have worked just fine. The error message seems to be about the browser's incompatibility with this build in web assembly. Though, other than that, I genuinely don't have more ideas about it.

Is the browser up to date? Perhaps retrying after the browser is updated may help? Another way is to retry running it in an incognito/private mode and see if it works. If not, I would give it a try in a different browser app, though that can be quite a hassle to install new browser on your side. :( If you're still interested in trying though, feel free to try these ways out!
