posh-git can cause problems with Git LFS

[adaviding]

System Details

• posh-git version/path: 0.7.3.1
• PowerShell version: 5.1.26100.2161
• Git version: 2.47.1.windows.1
• Git LFS version: git-lfs/3.6.0
• Operating system name and version: Windows 11 Pro for Workstations, 24H2, 26100.2605, 10.0.26100

Issue Description

In specific cases (for some git repos with specific file contents), Git LFS will freeze when used. This only happens when you execute commands from powershell while poshgit is installed.

The following is a perfect repro on my machine. Ensure that git lfs is installed (git lfs install). Pull down and unzip the repo_folder.zip from this gfolder.

Using powershell with poshgit installed, execute the following:

cd repo_folder
git init
git add *

You will notice that the command always hangs.

Upon further inspection with Sysinternals Process Explorer, you can see that git-lfs.exe is basically running (forever). If you go to Find / Find Handle or DLL ... and search for repo_folder, you will see that git-lfs.exe appears to be stuck while working on a specific file.
