Microsoft Security Update causing Monarch to fail with 'Cannot create temporary work file.'

​​

Our investigation found that KB4480970 2019-01 Security Monthly Quality Rollup for Windows 7 x64 contained one or more patches that is causing Monarch to fail when opening certain projects. The error dialogue box titled 'Cannot create temporary work file.' appears almost immediately.

We confirmed this by uninstalling this KB and testing the Monarch project with success.

We have applied an updated patch that was to address issues found in KB4480970, but it has not resolved the error.

Has anyone experienced similar issues and found a solution?

Thank you!
