Apologies if this has already been asked elsewhere.

I have previously been using XRF mapviewer with no issues on my MacBook pro (fully updated). 

Larch recently prompted me to update to the newest version, and following this, XRF mapviewer seems to be unable to open (tries and then immediately closes without any window ever opening). Oddly, all other programs in the Larch folder still work as normal.

I've tried removing Larch, redownloading and reinstalling, and still have the same issue. Any suggestions would be much appreciated - I'm definitely regretting the update currently!

I was also curious if there's somewhere I could just download an older Larch version? 

Thanks in advance,
