I have hast updated to the last version of muse (18.1). As a tried to export an existing site with no changes, the application crashed. After testing some pages I could focus the problem to a simple slideshow from muse, that I placed into an accordion. So if I disable the slideshow, everything ist fine. But starting with the even empty and complete resetted widget, the program shuts down with the alert:
I really cannot find an answer to this alert and it´s not a problem in the master page.
Sorry for the inconvenience caused.
However, would you mind sharing your .muse file with only the affected page and object, so that we can investigate and try fixing it?
For sharing the file you can follow the steps explained here - https://forums.adobe.com/docs/DOC-8652.
I reduced the project to 2 nearly similar pages (using the same construction with different content).
The one, that woks fine is named "kurse". The second page which causes the problem is named "mini_kurse".

Thanks for your help.
Thanks for sharing your file.
After doing some tests I narrowed it down to a slideshow widget which you have embedded into an Accordion.
However I deleted the same a tried to recreate that again and now wit works fine.
You can find the .muse here -
