I had the same problem for 2019. This is what I did and it worked. Thanks to Jeff. I have Windows 10.
YES, IT WORKED! I had seen a post earlier that suggested changing the TEMP&TMP files in the env. variables, but I changed the 2 files in the "System Variables". This time I changed the variable in the "User Variables for <computer name>". The original Temp file address was: C:\users\<computer name>\app data\local\temp\%userprofile%\appdata\local\temp. The TMP address was the same. I changed both to C:\temp, and the files now work. FYI, in the "System Variables", both TEMP and TMP are C:\windows\temp.
