server manager crashing

We had updated quickbooks and installed a windows .net frame of 4.7. Server manager then was crashing. We have uninstalled quickbooks and removed all updates since that previous date. Server manager still continues to crash. This is the CLR20r3 error we are getting. How does this get resolved?
