@proshor In the Settings Menu when you select Privacy and Security, in main window there is a Title
Privacy protection
Block ads and surf the web up to three times faster
Block trackers
Make sure these 2 settings are off.
I use uBlock Origin as my Blocker including while using Yandex and they work fine together in my situation.
If you still have trouble try another Browser for Yandex and if you have issues with the other Browser it is more than likely a system issue.
