Project is in BuiltinRP. I don't think this issue is render-pipeline specific.

Steps:
1. Open attached project (CamAni.zip)
2. Open camani scene, hit play
3. Observe GameView

Reproducible:
2022.1.0b4.2571 (0b1e54378c16) - animation is broken, on Hierarchy select "camera1", observe FieldOfView is being set to "1e-05"

2021.2.16f1.4522 - same

Not-reproducible:
2020.3.27f1.1527.3 (e759542391ea) - animation is fine

Workaround until fixed:

Make sure that all cameras with physical value have the field Physical Camera activated before upgrading.

When encountering files in this state, Re-import with cameras off, then back on. This restores the original animations.
