Teamspeak only has a black screen after start

Try running the client with the parameter --no-sandbox or running it as as administrator and check if an anti virus is maybe blocking it from loading. If none of these steps help, try to reinstall the client and also delete the folders manually. If you are using a really old graphics card the UI will not load any longer. Make sure you are using a graphics card that still have drivers that are updated.
