Launch Settings of your phone and open Application Manager.
Now tap on Galaxy Apps and then tap on Storage.
Now tap on Clear Cache and then check if the problem is solved.
Solution 2: Use Samsung Smart Switch to Update the OS

Now on your PC, Download and install the Samsung Smart Switch.
Now connect the mobile device to the computer with a USB cable and launch Smart Switch on your PC.
If an update for the device is available, you will be prompted to update. Then follow the prompts to complete the update process. Do not power off your system or mobile during the update process. Also, do not remove the USB cable until the completion of the process. Moreover, do not use the phone for any purpose during the update process.
After completion of the update process, check if the processing failed error has been resolved.
Solution 3: Reinsert the SIM
You may encounter the error under discussion if your phone is not recognizing the SIM. In this context, removing the SIM and setting up your phone by using Wi-Fi may solve the problem. You can also try another SIM with a different prefix.
Power off your phone and remove the battery of your phone (if possible).
Now remove the SIM card from your phone.
Now power on your phone and join a Wi-Fi network (try to use a hotspot from another Samsung phone).
Then try to sign-in using your Samsung account and check if the problem is solved.
If so, install all the products related to Samsung and make sure that the sync for the account is enabled.
Then reinsert the SIM. If you are a frequent international traveler, then try to use an international SIM (previously used with the phone).
