Paru leaves directory with broken permission after a build failure which it can't deal with

[Timicasto]

Affected Version

paru v2.1.0 - libalpm v15.0.0

Description

As soon as paru -Bi . fails, it will leave the pkg directory in d--x--x--x permission, and panick at the next time it got built, now I've seen it failed in prepare() and build(), all ends up with the same issue

Output

==> ERROR: A failure occurred in build().
    Aborting...
error: failed to build 'chromaprint-fftw-1.6.0-1':
