I must have missed your last post and, of course, I cannot reproduce the problem, but I think I found the real cause, checking your log better:
- YOU ARE USING the 32 bit version of Couatl in P3D V5, that's likely because you modified by hand the add-on.xml to do so, since our installer obviously configure it to use the 64 bit version, which is the one to use with P3D 4 and 5.
Or, perhaps another add-on that manages the add-on.xml files might have replaced the correct add-on.xml with a very old version, maybe coming from years ago, when we used a single 32 bit executable for FSX and P3D.
So yes, of course it's to be expected having issues when using the 32 bit version of the program in P3D V5 since, after we released the 64 bit version, in September 2020, we don't test the 32 bit version in P3D anymore, it's remarkable it even starts once...
