I'm afraid that linuxdeploy https://github.com/linuxdeploy/linuxdeploy-plugin-qt used by CI bundles libssl.1.1 instead libssl.3.0, anyway installing libssl.3.0 to the system should fix this, @paukert can you check it please?

https://learn.microsoft.com/en-us/windows/win32/com/schannel should help, Qt6 provides qschanel plugin

As far as I know I have not manually installed OpenSSL 3 on my system before. Import & Sync from/with ORIS is working despite messages in log (see first post of this issue).

Even if I installed OpenSSL 3.1.2, the error is still shown in the log.

Help → About QuickEvent:

Are these files necessary in QT6? They are copied to installation folder by:

quickbox/.github/workflows/installer.yml

Line 66 in 6334201

cp libssl-1_1-x64.dll libcrypto-1_1-x64.dll '${{ github.workspace }}/install/bin/'

I'm not sure, whether marked libraries are not used by postgres.
