Upgrading to C8: Z-Wave Device Connectivity Issues

I recently upgraded my system to C8 after using C7 for quite some time. My setup includes around 20 lamps and switches using Z-Wave devices, which were working perfectly before the upgrade. After restoring my backup, all devices are visible in the system, but they’re not responding. Checking the Z-Wave mesh table and logs shows no devices listed at all, which is perplexing. I really don’t want to go through the tedious process of excluding and including all these devices again. Has anyone encountered a similar issue? Are there any steps I might have missed during the upgrade process that could resolve this connectivity problem? I’d greatly appreciate any insights or suggestions from the community.
