DS not responding after opening Outrun Cluster example

Steps to reproduce:

• Clear examples from Documents/QtDesignStudio
• Open DS
• Click Outrun Cluster tile in Examples to download it
• Click again to open it
• -> opens a bit slow but still in reasonable time
• Close and reopen DS
• Click Outrun Cluster tile in Examples to open it
• -> Project starts to open, then everything seems to get stuck and DS shows "Not responding" ~2 minutes -> then recoveres
• Did not see this with other examples, tried a few
• Did not reproduce on macOS
