What's causing my Reaper to suddenly crash?

[etamboni]

A certain project keeps crashing Reaper...all other projects are fine.

I opened this one, adjusted a fader while it was playing back and it crashed..

Now I can't play this project all the way thru, it gets 20 or 30 seconds in and crashes the program...

How does one track down the cause?

thanks,

Ed

From my Windows 10 eventviewer:
reaper.exe
5.3.5.0
58b590a6
TTS-1.dll
1.0.2.0
50511372
c0000005

C:\Program Files\REAPER (x64)\reaper.exe
C:\Program Files\Cakewalk\Shared DXi\TTS-1\TTS-1.dll
ecdad3b1-7c22-44a1-9ac3-f1fb220594d5


-So it's got something to do with TTS-1.dll?
That's my Cakewalk piano VST...have been using it for years w Reaper, no problem...

and am using the TTS-1 in a couple of other projects, no prob.

But this one project crashes everytime, maybe 20-30 seconds in.
