RW 8.5 STILL crashes on Preview

Upgraded 8.4.1 to 8.5. Still getting the crashes on Preview as per RW 8.4.1 keeps hanging. I’ve shared one of the affected projects with @dan and the team some time ago, but the problem persists.

Catalina 10.15.2, Stacks 4.0.3, Latest versions of Foundry/Foundation.

Luckily, 8.3 (get it here: works just fine, and having renamed the executable, it coexists…

Can you share a crash report from one of these crashes?

Hi Isiah,

The Forum won’t allow me to attach a TXT file. Should I just paste it here?

You can place it on something like Dropbox and post or DM a link.

It might help @isaiah if you included a small project file with the crash report.

Thanks Doug,



Shouldn’t we wait for the next Stacks update to go to this version 8.5 of RW? … And besides, do we have any news on the expected fixes of Stacks 4.0.2? …

Thanks to you.

Ne devrait-on pas attendre la prochaine update de Stacks pour passer à cette version 8.5 de RW ?.. Et d’ailleurs, a-t-on des nouvelles sur les correctifs attendus de Stacks 4.0.2 ?..

Merci à vous.

If you are experiencing this issue (which should be somewhat rare – unless there is more than one problem here) – but I would recommend sticking to RapidWeaver 8.4 for now if you do see this.

It is a non-trivial compatibility issue, but I will attempt to repair it as quickly as possible.

You can always keep an eye on the stacks bug tracker if you’d like to report a bug, comment on a bug, or check to see when something will get fixed.

Hello and thank you @Isaiah for your return, I hope your health is back, too…
For the moment, I will stay with RW 8.3 and Stacks 4.0.3: this configuration is perfectly stable for me (except small bugs that can be controlled with Stacks).

Bonjour et merci @Isaiah de votre retour, j’espère que votre santé est de retour, elle aussi…
Pour le moment, je vais rester avec RW 8.3 et Stacks 4.0.3 : cette configuration est pour moi parfaitement stable (sauf petits bugs maîtrisables avec Stacks).


A little update. We fixed a couple crashes – primarily after image edits or undo. Since it was a substantial change we’re going to beta test this one a few days before we release it.

If you’d like to try the beta I always release them to the public on the Stacks slack channel.

If you’d like an invitation to the stacks slack channel just visit: everyone is welcome and invitations are automatic.
