Trados Subtitling Preview Bug

Hello, 

I'm trying to resolve a bug related to Trados Subtitling. It occurs when I click on the settings button in subtitling preview - it makes Trados freeze and crash immediately (as shown on the screen capture).

Before that, when I open an .srt file, I also get the error message : "the object reference is not set to an instance." 

I should also mention that I'm using Trados 2022 (SR2 version) free trial version.

Could someone please help me fix the issue?
