We have a Windows 2016 Server running SSRS 2016 that has recently begun exhibiting a symptom where any attempted report execution immediately crashes .NET, preventing execution. We have undertaken very many troubleshooting steps (i.e. repairing .net, rolling back the VM, activating additional .NET features on the box, deleting SSRS encryption keys and re-establishing Data Sources) with no success, however we do have SqlDump files that we're unable to interpret that we suspect may have further clues than the SSRS logs / Event viewer are showing us. Are those SqlDump files something I would be able to upload here for analysis?
Some other tidbits:
.NET is crashing with exit code 80131506
The SSRS log reaches "Exporting public key / Importing existing encryption key / Call to GetItemTypeAction (PathToReportFile)" before immediately crashing and generating a dump due to fatal runtime error

Hi, any luck with finding a resolution for this? we're experiencing the same issues. weird because SSRS crashes only hen a handful of people try to generate reports
Hey Barnabas,
Yes, but unfortunately it hasn't led to much resolution, in our case it was the Trellix Agent (nee McAfee) causing every report rendered through a browser to fail, presumably due to some sort of conflict on port 80. But, nothing has been nailed down yet aside from the fact that reports will render successfully with the Trellix Agent uninstalled, and will fail with a .NET crash when the Agent is installed.
As a workaround, we've been running needed reports in a Report Builder instance installed on the SSRS box, which interestingly does not run into the same issues with rendering regardless of whether the Trellix Agent is installed
Hey Jonathan, we were able to resolve this thanks to your response. We re-installed the trellix agent but DID NOT install the advanced threat protection. also added more exclusions including all SQL server, SSRS and .Net framework

- **Upload Dump Files:** Unfortunately, I can't analyze dump files here. Reach out to Microsoft Support or tech forums for help.
- **Other Steps:**
- Check for Windows updates.
- Use diagnostic tools like Windows Performance Recorder.
- Review Event Viewer logs for more info.
Remember to back up before making significant changes! For detailed help, consider consulting Microsoft Support or an IT professional.
Dear future techs,
The specific issue with Trellix and SSRS has been identified, the two SSRS EXEs (ReportingServices and WebHost) need to be excluded from the on-access scan policy of the Endpoint Security Threat Prevention policy in Trellix. Once those EXEs are excluded, reports should execute successfully with no .NET crashes
Are those SqlDump files something I would be able to upload here for analysis?
No one of us from the community can analyse dump file, even because we don't have the required source code for.
You have to raise a ticket at Microsoft support.
