Beginning this morning in production, we can no longer generate PDF's. We upgraded from 20.2.19 to 20.2.34; works fine in our test environment, running Windows 2019 Full version; however, in production, we're running Windows Server 2019 Core. We tried rolling back to 20.2.19; however, the problem still persists. We're now evaluating if it's a Windows update or other that may have caused this. Using the trace below, can you provide any guideance?
