This could be a faulty sensor or you actually have an oil pressure issue.

We need to perform a test with a gauge to see if the pressure does drop and then rise again.

I attached the testing for this plus the process on how to replace the sensor if that proves to be the issue. So if the mechanical gauge does not fluctuate then the sensor is the issue.

Here is a guide that will help with this:

Let me know what questions you have and we can go from there. Thanks
