In current master, opening vgroup modifier test file from svn's test repo (lib/tests/modifier_stack/weightvgroup_test.blend) and switching to third TEST_3 scene crashes with following backtrace (ts->sculpt is NULL):

@Jeroen-Bakker I suspect that one might be for you? Confirmed same crash on 2.83 as well.
