    Found the issue. Try running

    setfacl -R -b <directoryname>

    where "<directoryname>" is the directory with the build. It might have the special access privilege set.

    I'm having the same issue and unfortunately your fix above doesn't work for me @dsb04163 did you manage to fix it another way? Thanks in advance!
