Game freezing with long tabs names

[VitalRus95]

I used to have three tabs in my menu: On foot, In vehicle, About. Then I added General tab as the last but one, but the game started to freeze without any log. When I use the previous tabs names or On foot, In vehicle, General, everything works fine, including the new tab's content, but having four of them breaks the game.

Also, when I turned off auto-resizing in ImGui.Begin, the game stopped freezing, which makes me think the issue is connected to ImGui figuring out the window size.

This is the screenshot of how the menu looks like before the freezing occurs:
