2. Click on Virus & threat protection.

5. If yes, click the Allow an app through Controlled folder access option.
6. Click the Add an allowed app button.
7. Click the Recently blocked apps option, find Nero applications. Or browse to Nero installation path and add Nero applications: "nero.exe" (with full file path,e.g. C:\Program Files (x86)\Nero\Nero 2019\Nero Burning ROM\nero.exe, C:\Program Files (x86)\Nero\Nero 2019\Nero Vision\NeroVision.exe, C:\Program Files (x86)\Nero\Nero 2019\Nero MediaHome\MediaHome.exe, etc.)
8. Restart Windows and recheck Nero applications.
