@dm-korottsev Can't replicate here. Start trying if it happens using a new QGIS profile.

I met this today on linux latest master. Also happens on clean profile, no plugins.

In my case, it seems to be caused by a layer created by the Freehand raster georefencer plugin, though the plugin is not responsible for the crash.
Here's a project with the layer.
