On March 11th, 2021, I completed my downloaded of the full node from Bitcoin Core, (Bitcoin-0.21.0-win64-setup), on my Intel(R) Core(TM) i7-10700 CPU @ 2.90GHz - 16.0GB, Windows 10Pro.
I created a new wallet with encryption and I named it.
The "get new address" box remains grayed out.
After unlocking with "passphrase"  100),
Console command "getnewaddress" was unsuccessful. "update" says I'm wallet version 169900.
Node is fully synced and has remained in operation, with "check box" saying up to date, and with 10 active connections to Bitcoin network.
I haven't seen any new problems reported, with this issue, since 0.21.0 release. I'm pretty sure I've tried and was unsuccessful with all other suggestions for the same issue.
Any ideas are greatly appreciated. Further, I'm a boomer noob, who left programming after the mouse was introduced.
Uggh! Wondering if I should delete node and start over without encrypted wallet?
