The Problem

There is no problem with the camera itself, it can be turned on normally, it can be used normally, and it can also be kept running for a long time without crashing. However, when the web interface clicks on restart, there is a chance that the camera problem 0x00000004 will be incorrect
Clicking on restart or upgrade again has no effect, and can only be restored to normal after the power is physically turned off

[RaunoVV]

Encountered same error few days ago. Unplugging/plugging back in fixed it... im on v16.0

[buEtz]

Currently encountering the same issue here after a reboot, also v16.
Unplugging didn't change anything.

[caco3]

If you would have studied the log, you would have seen this:

[0d00h00m16s] 2025-06-05T14:26:10 <INF> [TFLITE] Trying to load the model. If it crashes here, it ist most likely due to a corrupted model!

[0d00h00m00s] 2025-06-05T14:01:51 <INF> [MAIN] =================================================

The timestamp of the last line starts again at zero, thus indicating that the device restarted.
So please select a different model or replace it with a non-corrupted one.

[hiatsu0]

Just updated my device from v16 RC5 to v16 proper, and had this kind of error. Tried a few reboots via web UI, and also another OTA but only hard reset by cutting the power helped.

Have seen similar issues with other board as well, so I think in these cases the Wiki or error message could suggest power cycling as first action?

[SybexX]

Apparently the camera hangs up and then only a hard reset(cutting the power) brings something.
I believe that it is due to the new I2C driver that was implemented in the ESP-IDF.

[bakacak10]

have the same problem. Have v16.
Only the power physically off and on again helps.
