Perfect, thank you!

You are right. Printing the algo was missing in gnupg22.

For Beta-75 it looks similar judging from my first tries.

I managed to get the same "loading certificate" message several times in a row on this test instance by stopping and starting Kleopatra in a row twice. After removing the Signature Card 2.0 this did not happen again in 5-6 tries, although I collected 2 lingering listing processes again (not both started on the same startup). Even import of a X.509 certificate worked.

Next I managed to have one gpg and one gpgsm process each left over from the last execution of Kleopatra.
After starting Kleopatra new anyway, again "loading certificate cache" and an additional pair of gpg and gpgsm listing processes start.

Had a occurrence of the never ending "loading certificate cache" issue again.
There was a leftover gpgsm process from the previous tests (although Kleopatra warned when I closed it, that processes still running in the background were there and would be aborted).

@ebo Thank you for your continuous testing.

Unfortunately, this seems not to have ended the sporadic hangs.
I just saw a hanging initial keylisting with gpg4win-beta-70 which has gpg 2.4.6

My fault: All my test had the relax flag set which is so common to me that I did not thought about this. So you fix is for the case that no flag has been set for a fingerprint.

(Please don't set a milestone tag for a fix to an already released version - we use the milestones to track done tickets). Use instead the branch specific tag so it ends up on the workboard.

Fix backported to 2.4

Passing ticket to werner to consider backports.

I suggest always updating modifications which are "exportable".

I do not want to do that for 2.2.45 (T7255) because we want to do that release RSN

works for VS-Desktop-3.2.94.2-Beta (Beta for VSD 3.2.4)

Porting to 2.2 was straightforward - we won't give it an extra QA run.

gpgme should handle lists correctly. In Kleopatra those options are not shown in the configuration dialog because they are GC_LEVEL_INVISIBLE, i.e. Kleopatra can read them programmatically but they are not shown to the user.

While testing this I noticed that only the last adsk or trusted key is listed. Thus several assurances of this options are not properly represented. See T7313

Fixed for master. Let's first test this with kleopatra.

Done for 2.2. It is already in 2.4.

Will do.

werner: Can you also backport listing of "default-new-key-adsk" with gpgconf so that Kleopatra can check whether a default ADSK is set?
