It's very hard to have useful anonymized telemetry. In this case, you actually need at least a partial memory or register dump to understand what's going on, but those can contain sensitive data that the failing code was processing. Telemetry doesn't have to be 100% anonymized - it can (and in some cases needs) to contain PII, just needs to be collected respectfully and transparently. Ask the user before sending something, and let the user review it. The user can then make their own decision.
