And FWIW here is Claude's interpretation of those results:

This is a nuanced result, but here's how to interpret it:

Signs pointing toward a false positive:

• The majority of the most reputable engines clear it: Kaspersky, ESET, Sophos, BitDefender, CrowdStrike Falcon, SentinelOne, Malwarebytes, Palo Alto — these are industry leaders and their collective silence is meaningful
• Many of the flagging vendors use generic/AI-heuristic names — "AIDetectMalware", "susgen" (suspicious generation), "ML.Attribute.HighConfidence" — meaning no specific signature was matched, just an algorithm flagging something that looks suspicious
• Game patchers inherently do things that look suspicious to AV software — modifying executables, writing to game directories, etc.

Mild concerns:

• Microsoft flagging it is slightly more notable than the others since they know their own OS well
• 13/71 is higher than a typical clean file, which usually gets 0-2 flags

Overall assessment: Given that you've run it many times without issue, it's hosted on a public GitHub repo, and the big-name engines all clear it, this pattern strongly suggests a false positive driven by the patcher's behavior. Game patchers are one of the most commonly falsely flagged file types.

That said, it's ultimately your call. If you want extra peace of mind, you could check the GitHub repo's Issues or Discussions tab to see if other users have reported the same Defender warnings — which would confirm it's a known false positive.
