OpenSSL AES Decryption fails randomly C++

[WuJinze via openssl-users]

Dear OpenSSL Group,
    Greetings. I was working on writing simple aes encrypt/decrypt wrapper 
function in c++ and running into a strange problem. The minimal reproducible 
examples in gist seems working fine but when i uncomment lines 90-92, it will 
fail to decrypt randomly. Can someone help me to figure out what's wrong with 
the code?    Here is my code: OpenSSL AES Decryption fails randomly C++ 
(github.com). OpenSSL version is OpenSSL 1.1.1f. G++ version is 9.4.0.Regards, 
Jinze
