1. Reproducible with 2 Player instances → one server Player, one client Player
2. On Windows, the IP can be found with the following cmd command {{ipconfig -all}}
3. Since the issue is reproducible in the 2022.2 stream it is highly likely that it is reproducible in the 2022.3 stream as well
4. In the internal comments there is a link to the Logging Package issue
