Answer by Simon Morgan for Low disk space after filling up C:\Windows\Temp with .evtx and .txt files

I was having an issue with my Windows Store applications refusing to update and the only clue I got was the error code 0x80070005.

I fixed it by updating Windows 10 to version 1903. After doing that not only do my Windows Store applications update fine but it also got rid of the issue with my Windows temporary directory filling up with EVTX files.
