I believe this was fixed by T7386. Or it is now no hard lock up by T7402.
So, let me close this ticket.
If any new symptom, please add information into T7396.

I can say it's fixed in 2.4.7.

Fixed.

I also checked this on Windows 10 with light, dark and high contrast (theme No. 1) colors:

Gpg4win-Beta-94: does not work here, but as the workaround still works, we have no regression. So I remove the vsd33 + gpgcom tag

Gpg4win-Beta-94: ok

Gpg4win-Beta-94: done

Gpg4win-Beta-94: works

Gpg4win-Beta-94: works

With Gpg4win-Beta-94 now all is fine, even own deactivated certificates are now shown (using the "Disabled" filter) in bold font

Fixed in Gpg4win-Beta-94
