[Unable to launch any games via Retroarch directly from Launchbox since upgrade to 11.9]

Well mjandhj820, it was not that exact problem for me, I had found these articles and confirmed I did not have that box to use quotes checked.
But. I did have the box below checked to use filenames only, not the full path. I unchecked this box and tada ... all work now.
Not sure how it got changed, but I can see why it would cause problems.

In any case, you are a gentleman, thank you for posting your findings and screenshots!

[Unable to launch any games via Retroarch directly from Launchbox since upgrade to 11.9]

Hello,
I've tried a number of fixes for this but no success.
The xml files seem ok (I.E. emulator / platform GUIDs are consistent) but retroarch will not launch when double clicking a game icon.
This happens for all cores except Saturn (Beetle), which launches Retroarch, but then errors with "Failed to set last used disk" .
This works fine directly from Retroarch, with same cores, same ROMs/images.
I can also launch games fine when using other emulators inside of LB (I.E. I use native ppsspp and Dolphin and not the RA cores for these).
I can right-click a game in LB -> Open RA, load the game and core and that works fine as well.
This was working fine before 11.9, and before I loaded SNK Neo Geo AES platform + ROMs.
The logs have no info, or I don't which logging to enable.
I removed the "SNK Neo Geo AES platform", launching LB as Administrator, still same issue.

I'd rather not have to reload the entire library/art/vdeos...etc.
