Hi, I'm Bernard. I'm happy to help!

Based on the error logs, the issue appears to point to ucrtbase.dll, a core component of the Microsoft Visual C++ Redistributable package, which may be corrupted or missing components. To sort out the issue, kindly follow the steps below:

Repair All Visual C++:

Press the Windows key + R and type:

appwiz.cpl

Then press

OK, Right-click each Microsoft Visual C++> Click Change> click Repair

Note: Do this on all Visual C++ Restart the computer and check

Method 2. Download and install Visual C++ from the link below:

Kindly download and install X86 and X64:
