Crash in 2.0.01

[Livingstudios (Kris Livingston)]

If there is a bug reporting form or category, or if there’s an existing topic on this, I apologize for missing it. Lightburn crashes when I start a specific job. The details of my job and setup are as follows:

• Running on a 2018 Mac mini with Intel Core i7, 32GB RAM, 500GB SSD, running MacOS Sequoia 15.5.
• The Lightburn version that crashes every time is 2.0.01 RC1.
• Tested the same job with the latest 1.7 release, and it works just fine.
• Laser is ComMarker B6 JPT MOPA.
• The job is the sample spider for doing a 2.5D engraving on a brass coin.
• My settings match the ComMarker recommendations for this engraving. Material Settings are shown in the screen shots attached.

Aside from trying the older version of Lightburn, which solved the problem, the only other workaround that I tried was to reduce the number of passes from 256 to 255, but that didn’t help. Let me know if I can provide any additional info.

Thank you!

Hello Kris

Thank you for this report, very detailed!
We are aware of this very specific to Mac issue and it was identified by the Dev team for a Fix.

The current workaround is what you did, which is roll back.

We expect the fix to be deployed on the next Patch.

No. I am running on Win 11 and I get crashes on both my EMP ST50r and my Commarker Omni 1. This is a HUGE issue and needs to be resolved ASAP. I am not a hobbyist and it is ruining my customers items.
