Tracking session is freezing the Qfield App

[Ipickedausername]

Hello,

I have a configured layer with a tracking session enabled.

When I open the project, the form for the tracker layer opens and I cannot close it. The app seems to be frozen.
When I tap on the validate button, nothing happens, and I can't even quit the app by double-tapping the return arrow.

What's very curious is that I don't recall updating the app. It was working yesterday, but today it is not, even on the same project I used yesterday.

This error only occurs on the QField Dev version; it does not happen on the regular QField version.
