It sounds like you need to contact Creality to update the AppImage. Although https://forum.manjaro.org/t/creality-slicer-appimage-not-loading-qt-network-ssl-errors/143726 suggests that the AppImage does not contain the OpenSSL library. But the only 'omission' of X.509 functionality that I can see on https://www.openssl.org/news/openssl-3.0-notes.html is "X509 certificates signed using SHA1 are no longer allowed at security level 1 or higher. The default security level for TLS is 1, so certificates signed using SHA1 are by default no longer trusted to authenticate servers or clients." I'm not sure I'd want to be deliberately trying to undo a security upgrade.
