Camera not working after upgrade to 5.10.4

Camera not working (black screen) after upgrade to 5.10.4. I have tried almost everything to solve this problem - no effect. 

Please could you say how can I  solve this or return to the previous version? 

My laptop is Lenovo (if it matters), camera app on windows is working correctly.

Hmmmm, the problem fixed by turning off Kaspersky anti-virus  🤔
