The OP and many others, including me, started getting this problem after the January updates, so the problem was already there before this February update. In fact, I have not received that update yet. The last update I have for KB5007651 was received in August (Update for Windows Security platform - KB5007651 (Version 1.0.2207.20002)).
@Davyday,
I never got January 2023 updates for the security. Last kb5007651 I got 1.0.2207.20002 back in Sept 2022, it was working fine with 22H2 Builds 22621, but unfortunately, they sent it out also on 21H2 builds 22000.xxxx and that created a mess with those Builds and had to be removed.
Now this 1.0.2302.21002 was received on Feb 23, 2023, and it created the problems with LSA with current public Build 22H2 22621.1265.
Luckily, I found a way to fix the problem as I described in the other thread. You may check that out or stick with the bug, it is your choice. 🤷♂️
