Webcam preview freezes when adjusting color and camera focus

Hello,
I have a problem with OBS Studio that I cannot fix from a long time. I am using as a virtual camera to record instruction videos for different items I am selling. The recorder item always lays on a table below my webcam. When I open the OBS and camera is starting to focus on an object (or just a table) and adjust colors automatically it freezes very often. In most cases it happens when there is a little dark in the office room and I turn on a ceiling lamp. On a sunny day the problem appears very rarely. The preview from the camera freezes and the only option to make the camera working again is to deactivate and activate the source again. Then it starts to focus and adjust colors again. Sometimes this procedure fixes the problem, sometimes I have to deactivate and activate the source again. I have made a video using Screencastify showing that freezing. Please check it here: https://drive.google.com/file/d/19L7aqhDO19gAN7g2fxm3JeZExA3zI36Z/view?usp=share_link

When the camera gets focused on the item then the OBS is working with no problem until I take the item from the camera view for a few seconds and camera is starting to focusing again on table table. If I put a new item quickly under the camera then the freezing will not appear. I have also noticed that when I put a white sheet of paper or the item is white (or grey, or other light color) under the camera and start the OBS then the problem almost never appear. The camera focuses very quickly, colors are adjusting very quickly and the camera and OBS is ready to go. It's like the OBS have problem when the items under the camera are in darker colors. I have not noticed that problem earlier because I had a grey table under the camera. Now I have a wooden light brown table and from that moment the problem has started. Unfortunately, I have no option to get back to the grey table so I have to solve this problem. I am running a DELL 5050 i7-6700 desktop computer with only one GPU. I am more then certain that the problem is caused by a setting of the OBS because when I use the same camera but on my ASUS Zenbook this problem never happens. Also one thing worth noting, I have recorded the above video on OBS 27.2.4 because this version is more stable for me. The OBS 28 crashes more frequently so I switched back to older version. But I have uploaded logs from both versions when the screen freezed again:

Log from OBS 28: https://obsproject.com/tools/analyzer?log_url=https://obsproject.com/logs/bG_Ci0b-Y-aaQ9tI#entry_1

The OBS 27 showed in the log problem with Wrong YUV Color Range. I have changed the setting that was pointed in the log but the problem still was present. Both logs show problem with GPU but I do not know how to fix that problem properly as I done the steps mentioned and it did not help. Can anyone tell me which settings I should change in the OBS to prevent freezing again?
