C:\Users\runersystem\AppData\Local\.mabs\siml-mibs-mrunner-m99-w88\workspace\projects\develop\mizen-scri1\test1\

I'm not sure why with path length getting The system cannot find the path specified. (os error 3) error.

1. The account runersystem is local system user and member of Administrator and Power users groups.
2. Windows 10 to accept File Paths Over 260 Characters enabled HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem - LongPathsEnabled - 1
3. Windows Update performed
4. Antivirus Un-installed.
5. Disk cleanup (Using Disk Cleanup) performed.
6. chkdsk scan performed.
7. sfc /scannow command executed.
8. User & System variables no issues.

Still encountering the same problem with length folder path. Also checked on another Windows-10 system even in that also same problem persists.

Can someone let me know, what is wrong with directory length? Thanks in advance.

This setting only affects application using UTF-16, not UTF-8 (like Ninja does), because no idea, please ask Microsoft why they like torturing us all the time.
