It seems that you are using the Corona sky to light up the interior scene. When you will do the final rendering, you will use Corona cam.
If you need to isolate an object while working and see its preview in the Corona VFB, it may be overexposed to the Corona sky. In this case, you can lower the exposure in the tone mapping to avoid over-exposure. For your final cameras, you can use the "Override" Tone mapping feature or control the exposure of your interior cameras using ISO, shutter speed, and F-stop to get the desired results.
This could be a workaround solution for your issue.
