Update: should now be available, BitBucket staff was very responsive, and Sophos AV as well. Two false positives remain by VBA32 and Cylance, which do not appear to have proper mechanisms to report false positive (not very professional for an AV vendor IMHO).
Just a quick note: the DWScript repository on BitBucket is currently down (as are my other BitBucket repositories), as the account was suspended because some antivirus started flagging one of the older zips from 2017 as malware.
The issue is currently escalating and the antivirus vendor is hopefully being notified of the false positive, but if the issue cannot be resolved, the repository will be moved elsewhere.
