If we're talking about statically linked Windows here then the answer is 
"yes". For other platforms the answer is "maybe". In many cases calling 
OPENSSL_thread_stop() is not necessary at all - but statically linked 
Windows is one case where it is. The conditions around this are 
discussed in the NOTES section of this man page:

https://www.openssl.org/docs/man3.2/man3/OPENSSL_thread_stop.html

But, if OPENSSL_thread_stop() is necessary for your circumstance, then 
it applies even if you only use libcrypto.
