After building my PC I feel regret for not buying a Mac studio, Adobe Apps are not using 5% of the CPU power and I don't know why, I make all the adjustment that could be done but nothing works. 💔

That's expected. Almost all processing is done on the GPU. If you do an AI mask, it is all GPU for example. Shouldn't be that slow at all on your machine at least for raw files. If you're doing masks on enormous panoramas it can get slow if the image doesn't fit in the GPU memory but that is rare with modern GPUs if you're using straight raw files. If things are slow on your machine, check the performance presets whether it is using full GPU acceleration and check any settings in the GPU driver. Slowness on windows machines is often due to overactive antivirus software by the way that is scanning the catalog every time you touch any develop setting.

This took care of it for me!  Exclude Lightroom from Windows Defender Scans:Open Windows Security by searching for it in the Start menu.Go to "Virus & threat protection" > "Manage settings" under "Virus & threat protection settings".Scroll down to "Exclusions" and click on "Add or remove exclusions".Click on "Add an exclusion" and select "Folder". Then, add the folder where Lightroom is installed and the folder where your Lightroom catalog is stored.Adjust Controlled Folder Access:In Windows Security, go to "Virus & threat protection" > "Manage ransomware protection".Turn off "Controlled folder access" or add Lightroom as an allowed app by clicking on "Allow an app through Controlled folder access" and adding Lightroom.Disable Real-time Protection Temporarily:Sometimes, temporarily disabling real-time protection can help improve performance during intensive tasks. Go to "Virus & threat protection" > "Manage settings" and toggle off "Real-time protection". Remember to turn it back on after you're done.Optimize Lightroom Settings:In Lightroom, go to "Edit" > "Preferences" > "Performance".Enable "Use Graphics Processor" if you have a compatible GPU.Increase the Camera Raw Cache to 10GB or more.Enable "Use Smart Previews instead of Originals for image editing".
