The Safari browser on Mac constantly logs out of accounts

The Safari browser on Mac constantly logs out of accounts, including Google and Gmail. This has been happening for the last few weeks since updating the operating system to Sonoma 14.5 (23F79).

I tried deleting all website data from the browser and clearing the cache. But this didn't solve the problem. Everything is fine in the settings, cookies are allowed, cross-tracking is allowed, etc.

Who has the same problem? Is there a solution?

This situation is so annoying that I’m already seriously thinking about switching to Chrome, but I really don’t like it.
