Quick update to that, I deleted the temp/jsreport folder and ran the test again and got a different error:

29Remote Instance Error: Error: EPERM: operation not permitted, rename
'C:\Users\MyName\AppData\Local\Temp\jsreport\compile\jsreport-2.9.0-SJEB3Pyev~chrome-oSCDt25i7' ->
'C:\Users\MyName\AppData\Local\Temp\jsreport\compile\jsreport-2.9.0-SJEB3Pyev\chrome'

I appreciate the help so far.

I downloaded the example console app from Github and I am seeing the same issue, yes.

No luck with that. I also updated Visual Studio (running 2019) to the most recent version, did a pull of the code and rebuilt in both .Net core 3.1 and .Net 5 with the same result.

Following the installation of the .Net Core 3.1.22 and .Net 5.0.13 Security updates (KB5009193 and KB5009194), my application is no longer able to generate PDFs. I'm guessing it has something to do with one of these updates, but that's only because I'm out of other ideas.

This application has been running perfectly for over two years now and is approaching end of life, so I really don't want to find a different solution for generating the PDFs. Is anyone else with those two updates having issues? Just in case it is of help, I get the following error:
