Microg how to debug?

Hi all,
I use an app from my bank that relies on microg component.
This app is useful when transfering money from one account to another: then a validation is required, validation is handled and secured through this app.
I see some issues with a message from microg saying that the microg services had been abruptely interrupted.
logcat provides some information

After the third try, I succeed validating the transaction.
Nevertheless, is there a way to improve this situation ?

Ps: I’ve got similar issues with the ‘le boncoin’ app, but it is not a mandatory app for me.

Do you have SafetyNet enabled in microG settings? That’s handled by DroidGuard which is shown not working near the top of your log.
Last I remember that feature doesn’t quite work anymore anyway. Even with root and hiding tools/modules. Google keeps making changes plus other reasons.
The whole SafetyNet business has been a thorn in everyone’s side for a long time. I’ve never used or needed it.
Not really sure what the actual cause of your issue is though.
