std::thread crashing when ending Span and or whereever new std::thread is writtern in library(.so)

[bharat2002]

I am using opentelemetry as a shared library in my project. It is working perfectly when I am linking it dynamically in a exe but new std::thread is crashing when I am using it inside a shared library project.
Built opentelemetry and shared library(.so) project with c++ 17 dialect . Using a otlp http exporter
Attaching call stack when calling end on a simple span processor.

This may related to #3295 .

This may related to #3295 .

Actually I am just ending the span and creating batch span processor. I am not unloading so files. It is the happy flow.
