RenderDoc v1.9 MapsModelsImporter v0.3.2 (with every appropriate version) Blender v2.83.0 Chrome v80.0.3

I had to download the older version of Chrome because it couldn't open the browser after injection. In older version it works. I also had to download the older version of Blender, now sample file for RenderDoc v1.9 works. Anyway, I'm getting an error as in the title, I'm moving the cursor when taking a capture so I don't know where the problem can be.
