Bug Report: SU2026 / Fatal crash on startup with D5 Render LiveSync (Errno::EISDIR)

Hi Fredo,

The last update doesn't fix the D5 issue. Either way, we can only use one of them (LOTT or D5 Render). So now my entire workflow is blocked, and so is the workflow of other D5 and LOTT users. We really need a QUICK fix for this, please.

I am reporting a fatal initialization crash occurring on SketchUp 2026.1.2 when using the latest D5 Render LiveSync plugin alongside Lord of the Toolbars (v3.0a) and LibFredo6 (v15.9c).

The Master Toolbar (yellow wheels) becomes completely unresponsive, and all custom toolbars disappear from the screen.

The Ruby Console highlights an unhandled directory scanning error in lordofthetoolbarsmanager.rbe inside the ghost_command_register method. It appears the script tries to open a sub-directory as a file, throwing an Errno::EISDIR exception.

The main folder causing the issue is d5_converter, located at:
%AppData%\Roaming\SketchUp\SketchUp 2026\SketchUp\Plugins\d5_converter

Exact stack trace:

#<Errno::EISDIR: Is a directory @ rb_sysopen - c:/users/[username]/appdata/roaming/sketchup/sketchup 2026/sketchup/plugins/d5_converter>

Temporary Workaround found:
Renaming the d5_converter folder to _d5_converter allows LOTT to load correctly, but it completely breaks the D5 LiveSync connection. Downgrading D5 LiveSync to v1.6 also works.

It seems a simple check to skip directories (like File.directory?) during the ghost_command_register file loop would prevent this crash.

Thank you for your work!

Hello,
I have installed the plugin in the last 2024 version. But nothing happens, it is marked as installer but won't show up anywhere.

@fredo6
I exeprience the same problem in SU24 last updat.
Is there any way that the Menu search dialogue can be unblocked ? I would realy appreciate it to be available again on SU24.

Thanks !

Hello Fredo, it's been a while since the "Make Unique All Level" function doesn't work.

Also could you add more of native sketchup tools (with new icons) please ?

Thank you so much for your hard work !
