I have tried a lot of different way to solve the problem, but still nothing change.
1. Updated the latest version 11.0
2. Reinstall the Lightroom
3. Rename the catalog
4. Relocated the catalog
5. Run as administrator
6. Install the Microsoft Visual C++ Redistributable 2012 (x64)

Still error~ pls help me. The problem issue since I updated windows version

Problem solved

I updated the latest version Microsoft visual c++ from Microsoft.com
https://docs.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

When the problem still there, you need to delete those file then download the latest version (from dll-files.com) to replace.

1. C:\Windows\System32\concrt140.dll

2. C:\Windows\System32\msvcp140_codecvt_ids.dll
