I misunderstood based on your initial post. Since you just have software issues:
- Use alt + f10 at boot to trigger the Acer restore process (this will likely destructively restore the original OS so rescue your data FIRST if you need it)
- If you have another windows 10 device you can create a rescue drive to potentially fix your install or roll back to a system restore point

- Attempt some other repair methods on your device using 3rd party tools

Good luck and please report back with your results.
