IMU Broken?

Since a yesterday the IMU on my Nano 33 BLE Sense randomly returns the following Gyro values and keeps these at this level until I reset the board:

17:15:06.709 -> A:123.2910
17:15:06.709 -> B:500.0000
17:15:06.709 -> C:123.5352

I think these value's are the maxed out values?

Is the IMU broken?
