Under Windows 8.1, Adobe Drive crashes on File- Check In... when invoked from an Adobe creative application.

Question

I am testing my drive connector on Windows 8.1 (64-bit) using Adobe Drive (5.0.2) with Photoshop CC (15.1.0.148) and Bridge CC (6.1.0.116), and I find that if I use File->Check In... from the creative apps (I checked InDesign too), the application crashes inside of AdobeDriveUI.dll.  The crash happens as it attempts to display the dialog that solicits a Check In comment.
I have tried using both the 32-bit and the 64-bit version of Adobe Drive, but both exhibit the same issue.  I am quite certain that my connector is not involved, as the crash happens in native code that collects the version comment *before* my ICheckInHandler instance gets called. 
I am interested in any insight or work-arounds that might exist.  Thanks for any help!

Thank you for the Replay,
I performed steps provided by you , but it did not help.
on other hand, i have collected some more data regarding
this issue.
1. went to SAFE Mode and tried to run the application from USB
2. got Exception "The instruction at 0x00407038 referenced memory at 0x00000078. The memory could not be read"
some more info on setup :
we have a micro controller on board, some part of memory (present on board) is used to keep application and server. we can open this memory via USB connection to PC. then we can see all files present at this memory on PC (behaves like externally connected
USB Drive) . 
When we start this application . it will start the server . server will send 'request file' to controller soft. (this part is working fine), and controller will send back response , as soon as response file(RSP.txt) will appear in USB drive it will get corrupted
.(here RSP.txt file is present in controller USB decided memory but to open this we are using PC RAM). crashing of RSP.txt file will crash whole application. This RSP File is of FAT Type.
i have copied application in another external drive and tried to RUN application. it will not crash  . but USB can not receive the "RSP.txt" (as it is not in communication with controller soft). and problem is in response file.
