Thanks for reporting this.
This is caused by the openssl 3.0 update which is apparently included in Ubuntu 22.04. My plugin comes with oscrypto 1.2.1 which does not yet support openssl 3.0 apparently (Bug report:
https://github.com/wbond/oscrypto/issues/55 )
According to that bug report, this issue has been fixed with oscrypto 1.3.0 which was released in March, so in the next update I'm going to switch to oscrypto 1.3.0 and then that error should hopefully be gone.
