Seems to be the same as #196948 and also reported here xdebug/vscode-php-debug#949

I was able to reproduce it with Remote SSH to a Linux, but not locally on Windows. I was not yet able to reproduce this with the OSS build - tried it only on Windows.

Its not visible from the stack trace what the actual DA Error is that's initially causing this.
