@xuwei-k do you know how to fix that one? I haven't dug into Scala Native at all.

[SethTisue]

I put a call for volunteers on the #scala-native channel on the Scala Discord, perhaps some hero will swoop in

[LeeTibbert]

I took a look at the log above.

I suggest you contact @WojciechMazur and see if/when he can take a look at it. Wojciech is probably the only one with the expertise to track it down in finite time.

[WojciechMazur]

It's probably the same issue as with munit when some 0.4.x garbage file slipped into the 0.5.x artefacts https://github.com/scala-native/scala-native/issues/3881 Working on a fix, would make a release after ensuring it fixes the bug
