That's happens of the corrupted KERNELBASE.DLL file
The file KernelBase.dll is a DLL file stored in the system folder of Windows operating system. It is created automatically during the installation of the Windows operating system. KernelBase.dll is used to launch .exe applications. When it is corrupt, you will get .dll missing or not found error when you start the programs.

How to restore it ?
Fix 1
Execute the sfc/scannow command to replace a missing or corrupt copy of the kernelbase.dll file. Fortunately, the kernelbase.dll file is provided by Microsoft in at least some versions of Windows, so the System File Checker tool (the sfc command) should restore it.


Fix 2
Update your Windows system
Check if there are any new Windows-related patches or service packs available. The DLL error might be caused by an outdated Windows operating system. Try updating your Windows system and this issue may get resolved. Here is how to do it:

On your keyboard, press the Windows logo key and type update. In the list of results, click Check for updates to open Windows Update window.
Click the Check for updates button to update your Windows system.

Restart your PC when the Windows update process is completed. If this fix works, your program wouldn’t crash with the KernelBase.dll error again.

Fix 3
Run the program compatibility troubleshooter
This issue may also be triggered by a poor written program. If your program crashes with the KernelBase.dll error when opening or closing a program, or just when a program is running, it’s time to run the program compatibility troubleshooter.
The program compatibility troubleshooter can check whether that program is compatible for your current Windows operating system or not. Just follow the steps to run the program compatibility troubleshooter:

Right click the shortcut of the problematic program on your desktop and select Properties.

Click the Compatibility tab and click Run compatibility troubleshooter.

Click Try recommended settings to test-run program using recommended compatibility settings. Follow the on screen instructions to see whether this troubleshooting option works or not.

If it still doesn’t work, then run compatibility troubleshooter again and select the second option to choose compatibility settings based on problems you notice.
If the problem persists, adjust the following settings manually and select OK when you’re done.
Compatibility mode: If your program is not designed for your current Windows system, the program may crash with the KernelBase.dll error. Click the drop-down list to select a previous version of Windows system to test run the program.
Run this program as an administrator: If the program is not given administrator privileges, it may not run properly and may even crash with the KernelBase.dll error. Try this setting to give the program the administrator privileges.

Fix 4
Create a new user.
A quick way, suitable for all the latest versions of Windows, is to run the command prompt as an administrator and enter the command (we change the name and password to the ones you choose, use only Latin letters for the name, in this situation this can be an important factor)
net user temporaryusername temporary_password /add_
and press Enter.
After that, log out of the current account (via the Start menu, for example, in Windows 10 - clicking on the user icon - exit).
Log in as a new user, which will be available on the lock screen (the first login may take several minutes).
Try running the program that was causing the error.
