Server refused public-key signature despite accepting key!

I updated to the latest version today and the connection no longer functions. It has worked for past 5 years
I use sftp with pageant
Authenticating with public key "rsa-key-20140130" from agent
Status: Server refused public-key signature despite accepting key!
Error: Could not connect to server

I've just experienced the same after upgrading to version 3.56.2.
The server side is: sshd version OpenSSH_8.4, OpenSSL 1.1.1k 25 Mar 2021.
The corresponding server side logged: debug3: mm_answer_keyverify: publickey 0x____________ signature unverified: incorrect signature

Password authentication still works.

It works (again) after updating pageant to the current version (0.76).
