windows precompiled version not working

[vipcxj]

I downloaded windows-0.11.1.zip which has several executable files. I double-clicked to run tracy-profiler.exe and nothing happened, I ran several other programs and still nothing happened. I used the command line to run tracy-profiler.exe and it returned straight back with nothing outputted
My windows version is win10 22H2 (19045.4894)

@wolfpld You are right, After install Visual C++ Redistributable, it works. By the way, is tracy support c++20 coroutine? I use coroutine with asio. i can't find any examples about asio with coroutine, only one for fiber. I don't use fiber, I don't even see the co_await and co_return keywords in this example. I tried using ZoneScoped directly, but it prompts ZoneEnd to execute 2 times. The documentation mentions that ZoneScoped is based on the RAII mechanism, which as I recall works in coroutines as well, I don't know what happened.

Tracy "fibers" provide a general mechanism for async tasks. If you can push instrumentation around the C++20 facilities, things should be working.

here is my code to start the asio io_context tasks

            auto m_io_pool = std::make_shared<BS::thread_pool>();
            for (size_t i = 0; i < m_io_pool->get_thread_count(); i++)
            {
                m_io_pool->detach_task([self = shared_from_this()]() {
                    auto guard = asio::make_work_guard(self->m_io_ctx.get_executor());
                    try
                    {
                        self->m_io_ctx.run();
                    }
                    catch(...)
                    {
                        self->m_logger->error(cfgo::what());
                    }
                    CFGO_SELF_DEBUG("io ctx completed in thread {}", std::this_thread::get_id());
                });
            }

How to make tracy work with it? Currently I'm hoping to use tracy to measure the execution times of my various functions to find out where exactly I'm stuck

Here is my code:

                    do

If there is only zone wait_not_full, it works, However, when i add lock_blocks and zone copy_ready_data, profiler show "zone is ended twice". I think every scope only has one zone, it should end only once.
