Project search is not working

Hello.

After updating webstorm version to 2021.1 project search is not working. For example, I'm looking for "testing" keyword and I definitely know that the project has the word, but I received nothing as a result. The same thing with switching between different tabs ("In Project", "Module", "Directory") and different types of search (regex, exect match) 

Webstorm version: 2021.1

OS: Ubuntu 20.04

Example:
