`collectPaymentMethod` crashes randomly

[r2-pro]

Summary

In May, we have started to observe that collectPaymentMethod is producing crashes.

The issue is non-deterministic.

Other information

We haven't been changing the card reader integration lately. I wonder if it may be related to card reader firmware update? We are using only M2 readers.

Any hints how we can get more info for the issue?

@r2-pro Unfortunately I haven't been able to reproduce this crash. Could you share more information on your integration: How do you use collectPaymentMethod? What is in your SCPCollectConfiguration? Do you happen to have a payment intent ID and/or reader serial number that was affected by this crash?

[r2-pro]

We've added more logging to gather data, but for now we stopped receiving crash reports for the issue. Isn't that related with firmware update schedule?

No, it does not appear that the chart above correlates with recently released software updates. Do you have any further logging to offer @r2-pro? Unfortunately I still haven't been able to reproduce this issue.
