Short description of error
Dynamic Paint image sequence bake crashes if mesh has no UV layer

Exact steps for others to reproduce the error
With default startup file:

add dynamic paint modifier to cube
add canvas, set format to "Image Sequence"
in the "Dynamic Paint Output" panel, hit "Bake Image Sequence"

File ready for step 3: dpaint_crash.blend

Here I'm not too sure what would be the best way to address the issue, however the following patch does the trick:

diff --git a/source/blender/editors/physics/dynamicpaint_ops.c b/source/blender/editors/physics/dynamicp

+       if (STREQ(surface->uvlayer_name, "")) {
+               BKE_report(op->reports, RPT_ERROR, "Bake failed: no UV layer selected!");
+               return OPERATOR_CANCELLED;
+       }
+
        /* Set state to baking and init surface */
        canvas->error[0] = '\0';
        canvas->flags |= MOD_DPAINT_BAKING;

Though, if the UV layer selector is empty in the UI, it is still possible that the mesh has a UV layer and the operator will use that one, so not sure if cancelling the operator is the right fix here.

Also here's the asan output:
