I am using my laptop mic because my headphone mic isn't working correctly, so you may have a little issue understanding somethings but if you need help comment down below!\
Step 1: Make sure you have all your mods off your GTA 5 game. The mods include, LSPDFR, trainer mods, and possibly some other mods you've put in your directory. If you have any LSPDFR Plugins that folder will be removed automatically but it's recommended to backup your plugin so when you want to play LSPDFR you still have it.

Step 2: Ensure that you verify integrity of game cache, now this is for steam users only not disc users. To get to this specific spot, you will need to open your game. Go to 'Grand Theft Auto V' and right click it, click properties then you should be on the general tab when it opens up. Make sure you click the local files tab and go to the last box or the box closest to your current build number for your GTA 5.

If none of these works I recommend making sure you have a strong internet connection. The recommended connection is 3mb/s for download speed. For upload speed it is 1mb/s. If you are running lower then this, for example you are in the kb/s range then that's most likely why. I recommended seeing if you can get a new router or WiFi provider, or updating your WiFi in general such as getting a new router. Now some do actually have newer routers that can get you good signal and more in power or speed. It's also not recommended to have a satalite internet provider, because there is a few second delay and depending on where you live it can be slower then other providers. I would recommended seeing if there are different providers in your area that can get more signal.
