Saving of Screenshot failed SRC issue

[covfefe 35]

My client always fails to take a screenshot, prints "Saving of screenshot failed" error. 
I've confirmed that it's a C++ issue as I have tested my binary.exe on an untouched client and the same problem was there. I've tested an untouched binary.exe on the same client and there was no issue.

Syserr:

Failed to lock the surface (0x8876086c)

I'd really appreciate it if someone could tell me what to do to fix this.

Thanks in advance.
