Hi Eric, Thanks The session was created with version 1.11.dev202511070202 (2025-11-07) on a Windows 11 machine, this one can reopen it fine. But I cannot open it on the latest Mac build, downloaded 2h ago, dated Nov 24th (sorry don’t have the version number here) Is there a workaround ? Can I save this session in a multi-version-friendly format ?

We will work on getting sessions like yours to open in the release candidate. --Eric Eric Pettersen UCSF Computer Graphics Lab On Nov 25, 2025, at 9:13 AM, GOVAERTS Cédric via ChimeraX-users <chimerax-users@cgl.ucsf.edu<mailto:chimerax-users@cgl.ucsf.edu>> wrote: Hi Team, I’m switching between computers and platforms, but now I try to reopen CXS session it fails and I get To restore session: install Animations bundle version 1.0 or newer Unable to restore session: need to install missing bundle I’ve tried the very last version of chimeraX (daily built).
