      I upgraded my Qt version to 5.12.9, buf after the upgrade, the QtCreator cannot launch normally. If I click the QtCreator icon to launch, nothing will happen. And when I use command line to launch, the following error occurs:

      (qtcreator:3220): GLib-CRITICAL **: g_hash_table_contains: assertion 'hash_table != NULL' failed
      
      (qtcreator:3220): GLib-CRITICAL **: g_hash_table_insert_internal: assertion 'hash_table != NULL' failed
      Segmentation fault (core dumped)
      

      I reinstalled the Qt serveral times, but it doesn't work. Hope someone could help me figure this out. Thanks!

        @Phymin Try to start QtCreator with "-noload all" parameter - does this work?

          @jsulm said in Qt Creator cannot launch in ubuntu16.04:

          -noload all
          Actually, it's the same:

          ./qtcreator -noload all
          
          (qtcreator:8402): GLib-CRITICAL **: g_hash_table_contains: assertion 'hash_table != NULL' failed
          
          (qtcreator:8402): GLib-CRITICAL **: g_hash_table_insert_internal: assertion 'hash_table != NULL' failed
          Segmentation fault (core dumped)

            g_hash_table_contains: assertion

            I don't know whether any of them will help your situation, but if you Google for g_hash_table_contains: assertion you will see a number of hits which you might at least read through.

              Thanks for your reply. Yes,I do google this problem before I post the problem here, and I tried some of them, but I didn't find much useful information related to qtcreator exactly.
