OS Windows 7 Ultimate SP1

RAM 8.00 GB

VxKex 1.1.2038

Problem Using the latest MSYS2 MINGW64 environment, I had repeatedly encountered a problem with the git pull command. When I ran git pull with VxKex enabled in the console, it printed

Without VxKex, git would not start and I could not find the reason to this. How to solve that, thanks.
