Do you know why this is occurring and how to prevent it? It seems to occur often time. Thanks.

I think it's usually an AV or Windows Defender interfering with the unpacking of the Java runtime files. It should only occur as often as we update the bundled Java version, and then not again until the next time (potentially). We're not 100% why it happens though - we really just see it on Windows machines occasionally.
