All other keys work fine, but this one causes the system to crash. I've tried many widgets, and the result is the same. This situation occurs after executing the set_group statement.

GROUP should be create by group = lv.group_create()

not group = lv.group_t()

Yes, that's my mistake. I didn't use your framework but wrote a keyboard device from scratch. The strange thing is, when using group = lv.group_t(), it only crashes when running prev, but everything else works fine.

dunno why it would do that...
