git bash not working

[이지혜]

Hi, I have been using git bash (the recent version) on my Windows 10 x64 bit laptop. 

Unfortunately, git bash suddenly does not open, and I am facing a lot of trouble with my work.

Whenever I try to use git with the default windows command terminal (since git bash does not work), 
"0 [main] sh 1448 C:\Git\usr\bin\sh.exe: *** fatal error - error while loading shared libraries: C: cannot open shared object file: No such file or directory"
  errors like this appear.
Git clone, push, pull - nothing is working.

I have even tried reinstalling, configuring the PATH variables and so on, but the "fatal error while loading libraries" does not seem to be solved.

I would be glad to get some help.

Thanks.
