Hi @Shorty Pavlov ,
Welcome to Microsoft Q&A!
Does it only happen in Visual Studio? Can your mouse work on other apps?
Please check your mouse and ensure that the problem is not related to hardware.
If it is not a hardware fault, please temporarily disable all anti-virus software and do a full scan for your computer.
Then, update your VS to the latest version through Visual Studio Installer.
After that, disable all installed extensions under Extensions > Manage Extensions > Installed and create a new project to see if it works.
Sincerely,
Anna
