Everytime I try to sort inventory or retainers I am recieving this crash

"Faulting module name: ntdll.dll"
This is a file deeply integrated in Windows and it might be corrupt.

I would try this first:
Right-click the start menu and open a Command Prompt with admin privileges.
Type "sfc /scannow" (without the quotation marks) and press enter. Let it run, reboot computer and see if that fixed it.

The exception code 0xc0000374 indicates a heap corruption.

I would recommend running a malware scan. Google "Malware byte remover". It is a reference and it's free. If that doesn't help, remove unneeded background process.

Heap corruption does not just happen.
