What should I do if the computer cannot connect to ST-Link? You can try the following methods one by one.
method 1
Restart the computer.
Method 2
Make sure that your computer driver is installed. If not, you can see the driver installation link below.

If you can see this thing in the device manager, it means it has been installed.
Method 3
Find this software in the installation path. This software can update the firmware of the ST-Link module. ST-LinkUpgrade.exe.
The update here does not necessarily mean an upgrade. It may mean a downgrade to match the computer's keil software.
Click the device link, then click yes to start the update. Reconnect after the update, and you can use it normally.
