Working TouchGFX Project suddenly fails to build

[PFlor.2]

I have been working on a project for many months now with TouchGFX v4.20.  I was modifying some of the text strings I had defined in TouchGFX Designer and now the texts/TextKeysAndLanguages.hpp is no longer being generated.

When trying to start the simulator I see that it says something about an unexpected character (see below output).  This is halting any work I can do with TouchGFX anybody ever experience this??

Run Simulator
Generate
Done
Generate Assets
make -f simulator/gcc/Makefile assets -j8
Reading ./application.config
Unexpected character at -~
Cleaning generated files from generated/texts and generated/fonts.

Why no try next releases ?

[PFlor.2]

I thought about it but get scared upgrading tools in the middle of a project.  didn't see a way to update designer from the application, do I need to do a fresh install for a new release?

I guess something got corrupted somehow, I was able to go back to work I saved 3 days ago and start there.  Everything builds fine again.  Was able to incorporate everything I had done over the past 3 days and still works fine so I guess all is well.  Not sure how the TouchGFX project got corrupted but it did.
