Kotlin coroutines - dispatcher switch doesn't work

I have this code:

coroutineScope.launch(Dispatchers.IO) {
        if (openGraphParser != null && isActive) {
            Logger.info("Loading OpenGraph data for $link")
            val content = openGraphParser.getContents(link, messageText)
            Logger.info("OpenGraph data for $link received")

            withContext(Dispatchers.Main) {
                Logger.info("Showing OpenGraph data for $link")
                onOgDataReceived(content)
            }
        }

And I don't see the log: "Showing OpenGraph data for $link". The code inside "withContext(...)" is simply not called. Why? Can anybody explain it to me? The last log is "OpenGraph data for $link received". If I change it to

coroutineScope.launch(Dispatchers.IO) {
        if (openGraphParser != null && isActive) {
            Logger.info("Loading OpenGraph data for $link")
            val content = openGraphParser.getContents(link, messageText)
            Logger.info("OpenGraph data for $link received")

            ogDataContent?.ogDataLayout?.get()?.post {
                Logger.info("Showing OpenGraph data for $link")
                onOgDataReceived(content)
            }
        }
    }

than everything works fine with post within view.

In my opinion there is two case may occur

1. coroutine is running within a valid coroutineScope. If coroutineScope.launch(Dispatchers.IO) is not properly scoped and the coroutine is canceled or completed before reaching the withContext call, the code inside may not execute.

2. When using withContext ensure that you are correctly switching to the main dispatcher. If there are any issues with the main dispatcher (like if it isn't set up correctly in your environment), this could cause your code to fail silently.

so I would suggest you:

   coroutineScope.launch(Dispatchers.IO) {
    if (openGraphParser != null && isActive) {
        Logger.info("Loading OpenGraph data for $link")
        try {
            val content = openGraphParser.getContents(link, messageText)
            Logger.info("OpenGraph data for $link received")

            withContext(Dispatchers.Main) {
                Logger.info("Showing OpenGraph data for $link")
                onOgDataReceived(content)
            }
        } catch (e: Exception) {
            Logger.error("Error fetching OpenGraph data: ${e.message}")
        }
    } else {
        Logger.warn("OpenGraph parser is null or coroutine is not active")
    }
   }
