QGIS Distance Matrix execution fails

I am trying to use the distance matrix to measure the distance between a crime (input ID) to the closest subway entrance (target layer). The problem is that sometimes the matrix comes out with results, sometimes it doesn't and instead, the algorithm fails.

I get this error in the distance matrix log

Traceback (most recent call last): File

  Do your layers have the same crs?

The error code is not helpful for this alg.

A way that works for me is to ensure that both layer are in the exact same CRS (preferably projected) and to ensure that the output layer is not used by any process.

Trying to replace a layer that is already in use will cause this error, in that case simply remove it from the projet and it should work.
