Hi,

I installed

dv-mac-arm-1.7.1.dmg

but when I start the DV gui it does not launch.

I started from a terminal to see the log outputs and get the following error chain:

```
m902091:MacOS tn41$ ./run

Hello, thanks for reporting this.

Seems to be a bug with JDK21 and JSON date formats:

https://github.com/google/gson/issues/2689

https://www.oracle.com/java/technologies/javase/20-relnote-issues.html#JDK-8284840

We'll fix this in the next release, as a work-around you can just delete the offending DV preferences file, it's usually in:

$HOME/.java/.userPrefs/inivation/dv/prefs.xml

Have a nice day!
