Hi and thanks for reaching out. My name is Bernard a Windows fan like you. I'll be happy to help you out today.
Actually, I have the same problem and by following the steps below fixed my issue, I know some of these steps are already done, you have just skipped it if you think it will have the same result.
Method 1. Do clean boot:
A “clean boot” starts Windows with a minimal set of drivers and startup programs so that you can determine whether a background program is interfering with your game or program.
- In the search box on the taskbar, type msconfig and select System Configuration from the results.
- On the Services tab of System Configuration, select Hide all Microsoft services, and then select Disable all.
- On the Startup tab of System Configuration, select Open Task Manager.
- Under Startup in Task Manager, for each startup item, select the item and then select Disable.
- Close Task Manager.
- On the Startup tab of System Configuration, select OK. When you restart the computer, it's in a clean boot environment.

Method 2. Run memory diagnostic tool: The memory diagnostic tool is a RAM test to check if there are any issues with RAM.
- Press Windows key + R then type in mdsched.exe hit OK then restart the device.
Method 3. Set the PC to best performance:
Press Windows key + Pause/Break (or go to file explorer and right-click This PC and click properties)
Click on Advanced system settings> Under Performance click settings> Click Adjust for best performance and click OK
Note: this will reduce all appearance settings you have but will optimize the performance of the PC.
Let me know how does it go and I hope that helps.
