Cannot change private mode default search engine (no selector appears and breaks normal search too)

Description of the issue:
Hello, i encounter this problem on 2 PCs, trying to change search engine of a standard window works no problems, trying to change private mode search engine makes the link change in the upper bar but does nothing, and then if i want to change normal tab search engine does the same thing, after that i need to press another settings tab twice to exit from search engine one and to be able to choose normal tab search engine again.

How can this issue be reproduced?

  1. Open settings
  2. Go to search engines
  3. Click change private mode search settings

Expected result:
The selection window appears allowing to choose the search engine.
