Unfortunately, the latest beta does not appear to address the issue. Do you know whether this is currently being investigated and if we can expect a fix in the near future? I know it may be difficult for you to say, but about five years ago, we migrated away from the GCD API to the Network API due to crashes introduced in macOS 10.15 (Catalina). We would really prefer not to have to work on another workaround, especially since we have confirmed that the underlying GCD issues still persist...
