Then I find the issue in Openenclave https://github.com/openenclave/openenclave/issues/4680

How can I solve this error?

Hi,

This linker error occurs because we dont support Ubuntu 22.04 as yet. Ubuntu 22.04 comes with openssl 3 . OE and Mystikos work only on Ubuntu 18.04 and Ubuntu 20.04 which comes with openssl 1.1.1.
