I'm unable to change layers order in the layer tree. The 'drag and drop' stopped working and I don't know why.
There's no problem with Layer Order Panel; Control rendering order box is not checked. Restarting QGIS did not help. I tried to reinstall program after cleaning directiories (I think I got all of them) but it also did nothing. I was using QGIS 3.4. and I'm on 3.6. now.
I'm using QGIS for basic functions, no coding. I'm on Windows 10.
