Ganttproject crashes every 10 mins for no apparent reason on M1 pro Mac

I see there are some old threads on this. Is there any solution for running ganttproject on M1 Mac?

I dont know if I have the DMG version.

app version: 3.1.3103. the app says this is the latest version, and auto updates are enabled.

openjdk version “11.0.10” 2021-01-19 LTS
OpenJDK Runtime Environment Zulu11.45+27-CA (build 11.0.10+9-LTS)
OpenJDK 64-Bit Server VM Zulu11.45+27-CA (build 11.0.10+9-LTS, mixed mode)

The latest version is GanttProject 3.2.3247, and native Mac M1 support was added in GanttProject 3.3 Beta. You can download the beta from GanttProject - Download
