Not a question, but a finding after installation.
We had a user that consistently crash ArcMap on right-clicking just about anywhere within the software. There was also crashing when editing/updating using the Attributes window.
After submitting crash reports, uninstalls, repairs, updates, changing machines, and a lot of troubleshooting, we finally determined the culprit.
The user had installed Grammarly as part of their preferred software installation. After uninstalling Grammarly, ArcMap stopped crashing and has been running without crashing.
Passing this along for anyone who has "phantom" crashing and has Grammarly installed.
Happy Mapping 🙂
