Start a PyFladesk application got a ucrtbase.dll error on windows 10

I clone PyFladesk repository. Then create an application for the example application by the command

pyinstaller -w -F --add-data "templates;templates" --add-data "static;static" app.py

It's OK. After I run the application with the command dist\app.exe. This app is automatically closed when it is opened.

The error message show in the event log.

Error module name: ucrtbase.dll，version: 10.0.16299.125 Exception code:0xc0000409 Error applicaiton path:D:\pyfladesk_test\dist\app.exe

Does anyone know how to solve this problem?.

Thank you.
