Hi there, surya-cb.

Unrecoverable errors when using QuickBooks Desktop are usually caused by a missing Windows or QuickBooks updates, data damaged, or computer issues. I'll share some steps on how to resolve this type of error when working in QuickBooks.

First, make sure that you have the latest maintenance release. Use this article as a guide: Update QuickBooks Desktop To The Latest Release. 

Second, use the Verify/Rebuild Data Utility Tool to detect data issues in your company file. Here's how:

1. Go to the File menu, scroll-down to Utilities,and then select Rebuild Data.
2. Click OK and follow the onscreen steps to save a backup.
3. Let the tool repair your file. It may take some time. QuickBooks may seem stuck, but as long as you can move your mouse, the tool is working.
4. Click OK. once the repair is finished. 
5. Go back to the File menu, select Utilities, and then click Verify Data.
6. Let the tool check your file for data issues.

Select OK if QuickBooks there are no data issues.Click Rebuild Now if the system detects an issue with your company file,

Aside from that, you can also run the QuickBooks File Doctor from the QuickBooks Tool Hub.

With regards to your second question, can you tell us what happens when you try to make Internet Explorer as your default browser? QuickBooks Desktp requires at least Internet Explorer 11 (32-bit). Here's an article for more details: System requirements for QuickBooks Desktop.
