Error whilst installing package from DEV to QUAL

Hi all,

We just tried installing our package on our pre-prod environment to test and unfortunately have met an error :

2020-10-23 10:24:19,373 System.UnauthorizedAccessException: Access to the path '_MetaInfo.json' is denied.

Compilation works without errors though.

Any ideas how to solve this ? We are on an on-prem version.

Thanks and lovely day !
