Z-wave issues after update to 105.5

After updating to 105.5, all of my z-wave devices were unavailable. As suggested in another thread, I restored to a previous snapshot, deleted zwcfg_0xe9973468.xml, and then upgraded. Now my devices show up in lovelace, but take forever to respond if at all. I’m running on a raspberry pi 4, aeotek stick through a usb 2.0 hub. Please help. I have about 30 nodes.

Here is [some of] the log:

I had this issue as well. Either all or large numbers of wave entities were unavailable. Many of them reverted back to manufacturer names rather than the custom names I had given them. I rolled back to a snapshot in the 103 release series and the problem went away. Not a fox, of course, but wanted to make sure that people saw the issue wasn’t just yours.

Turns out my issue was due to remodeling my kitchen. I removed 2 z-wave switches without removing them from the network. I just assumed i could pull them and the network would rebuild itself. Caused odd behavior especially when trying to access certain nodes that were through those removed switches.

I powered up the switches, removed them via the Z-Wave UI, healed network, all good again.
