LyX ⇒ Turn on Lyx debug on Windows?

[hmpws]

i am using Lyx 2.3 and it is just crashing randomly (no error message). It is crashing often enough to I want to find out why! I want to turn on the debug log to see why this may be.

In the Target field of the Windows shortcut, I did:
"C:\Program Files (x86)\LyX 2.3\bin\LyX2.3.exe" -dbg any

But I don't see any log file, I don't see anything there either even if I run the program with admin permission.

Where is the log file?

Thanks!
