Found 1 module(s) missing file: .Modules.wire/modules/ => /site/modules/.Modules.wire/modules//.Modules.wire/modules/.module
And I can already see my problem, I downgraded to 3.0.217 due to another bug.
After that, the problem occurred, just as you wrote, because .217 does not need this entry.
In the meantime, I have updated to .219, where the entry was created again. Without error message.
