Some issues with the desktop application are sometimes because of using a beta version (I’ve just learned about what beta means). This can be problems with syncing, connecting, starting up, and more.
Make sure that your version has a 4 in the middle (like the current one 149.4.4568) because that means it is a stable version. If you have a 3 in the middle (like 150.3.4987) you are using a beta version.
To turn this off, turn off Early Releases in your account settings online like this https://help.dropbox.com/accounts-billing/settings-sign-in/enable-early-releases. Then, install the current stable version by going here https://www.dropbox.com/downloading. You do not need to uninstall the desktop app beta. Just install the stable one over it.
