Same problem here with version 1506 on one of my two Windows 10 computers.
Don´t know what´makes the difference betweeen both pcs. Similar software, similar hardware.
Windows 10 start menu, info center, soundmix button gone after "Clean & Fix my computer" with extra safe settings and automatic repair.
Luckily I created a Windows 10 restore point before. The JV16 backup didn´t help to solve the problem.
JV16 exported lines (nearly 2000 lines) were kind of:
HKCR\AppX04g0mbrz4mkc6e879rpf6qk6te730jfv\Application\ : ApplicationIcon, 20, File or Folder "e:\Microsoft.XboxApp\Files\Assets\GamesXboxHubAppList.png" doesn´t exist
My programs and apps aren´t on e:\ but on c:\
If i looked up correctly with regedit, the corresponding entry in my Windows 10 registry rather reads
HKEY_CLASSES_ROOT\AppX04g0mbrz4mkc6e879rpf6qk6te730jfv\Application
:
ApplicationIcon REG_SZ @{Microsoft.XboxApp_14.14.16008.0_x64__8wekyb3d8bbwe?ms-resource://Microsoft.XboxApp/Files/Assets/GamesXboxHubAppList.png}
No idea, why JV16X 1506 interpretes such @{ entries as e:\ entries.

Downgraded to version 1502 and deactivated auto-update.
