    Description

      1. Open the attached project in Creator.
        I configured it on Qt 6.9.1 from the Online Installer
      2. Go to the line 
            p.drawT

        and trigger code completion.

      3. Press Enter to complete the line using drawText(),
        Creator crashes. On the command line I can read: 
        Failed to initialize instances shared memory:  "QSharedMemory::handle: doesn't exist"
QObject::disconnect: wildcard call disconnects from destroyed signal of ProjectExplorer::TargetSetupPage::TargetSetupPage
SOFT ASSERT [16:50:12.615]: "!clangToolPath.isEmpty()" in /home/qtrob/dev/src/creator-17/src/plugins/clangtools/executableinfo.cpp:219

          • P1: Critical - Urgent and Important, will STOP the release if matched with set FixVersion field. This includes regressions from the last version that are not edge cases; Data loss; Build issues; Flaky tests; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable. This is the highest possible priority for requirements.
