ValueError: path is on mount 'D:', start on mount 'C:' when scanning repositories on different mounts

[aswin-kevin]

Describe the issue
I am encountering an issue with the Checkov executable on a Windows 11 machine when scanning repositories located on a different drive mount than the one where the Checkov executable is located. The issue causes a ValueError indicating that the path is on a different mount, which prevents the scan from completing successfully. This issue was reported and closed in 2021, but I am still experiencing it in December 2024.

Examples

# Running the following command in PowerShell
.\checkov.exe -d D:\projects\others\fooworld --skip-path target -o json --output-file-path D:\projects\others\fooworld\iac-test-res --framework cloudformation dockerfile helm json yaml kubernetes terraform terraform_plan --quiet

Expected outcome: The scan should complete successfully and produce the expected output file.

Additional context
This issue was previously reported and closed in 2021, but it seems to persist. Any insights or suggestions for a workaround would be greatly appreciated.

It is happening for the frameworks "dockerfile" and "terraform" (found this while doing a random check).
