Qt Creator cannot launch in ubuntu16.04

[Phymin]

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)

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

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.

@Phymin You could also try to update graphics driver
