Hi,

if you are using an Apple Mac, I would recommend some maintenance actions:

Copilot summarised it as :

Resetting the NVRAM (non-volatile random-access memory) and PRAM (parameter RAM) on your Mac can help resolve issues related to settings such as screen resolution, time zone, startup disk selection, and more. Here’s how you can reset them:

1. Shut down your Mac completely.
2. Turn on your Mac and immediately press and hold the Option (⌥), Command (⌘), P, and R keys together.
3. Keep holding these keys for about 20 seconds. During this time, your Mac might appear to restart.
4. Release the keys after the 20-second period or after you hear the second startup chime (for Macs that play a startup sound) or see the Apple logo appear and disappear for the second time (for Macs with Apple T2 Security Chip).

For Intel-based Macs, this process will reset the NVRAM/PRAM. However, for Macs with Apple Silicon, there is no NVRAM/PRAM reset procedure due to the different architecture. Simply shutting down and restarting your Mac should suffice¹²³.

After resetting, you may need to adjust some of your settings like sound volume, screen resolution, or startup disk preferences through System Preferences.

If you continue to experience issues after resetting the NVRAM/PRAM, it might be worth considering other troubleshooting steps or contacting Apple support for further assistance. Remember, resetting NVRAM/PRAM is safe and does not affect the data on your Mac¹.
