If your Acer is still running Version 1703 (April 2017) of Windows 10, it should be updated to Version 2004 (May 2020).
Because your Acer is obviously a few years old and the upgrade process did not work for you, you should do a clean install of Version 2004.
Go HERE, then click Download tool now, then download and save the MediaCreationTool2004.exe file.
After that's done, close all open browser and app windows, then double-click the saved file to run it.
Follow the directions to download Windows 10 and create a bootable USB thumb drive or bootable DVD.
After that's done and you've backed up any personal data that you don't want to use, you can use that newly-created bootable media to do a clean install of Version 2004.
What's the exact SNID number on your Acer?
