When I switch from default UI theme to night mapping, I get this error message:

An error has occurred while executing Python code: 
 
RuntimeError: wrapped C/C++ object of type ClusterPointsAlgorithm has been deleted 
Traceback (most recent call last):

After I close the error message, QGIS stays in default UI theme, and no further issues occur. QGIS does not crash, so this is different from #26557.

I have no idea why the error message mentions the ClusterPointsAlgorithm. This is a blank project, so there aren't any layers using the clustered point style.

I had the same issue with QGIS 3.2.0.

That's a bug in the cluster points plugin, not qgis.
