Studio Pro Page Editor crashes when clicking any + button for insert Widgets (TypeError: r is not a function)

0
Hi everyone,I'm experiencing a strange issue in Mendix Studio Pro and I'm running out of ideas.Environment:- Mendix Studio Pro 11.0.x- Windows- Issue occurs in multiple projects- Issue occurs for multiple developersProblem:Whenever I click one of the blue "+" buttons in the Page Editor to add a widget, the editor crashes and shows the following error:TypeError: r is not a functionThe error appears in the Page Editor component and prevents me from adding new widgets.What I've already tried:- Restarted Studio Pro- Rebooted the laptop- Waited several days and tested again- Reinstalled Mendix Studio Pro completely- Tested with different pages- Tested with different projectsThe issue occurs everywhere, not only in a single page or project.Additional information:- Existing widgets can still be selected and edited.- The crash happens specifically when clicking the blue "+" insertion buttons.- The problem started after I accidentally pasted a widget into the wrong location in the Page Editor. However, the issue now also occurs in other projects.Has anyone seen this before?Are there any known issues with Mendix 11.0.x, the Page Editor, or cached editor settings that could cause this?I've attached the error screenshot.Thanks in advance!

11.2.1 was released specifically with a fix for that. If you're still on 11.0, i'd recommend to at least upgrade to 11.6.x and see if the issue persists over there. If the issue would persist on an earlier version on 11.6 as well, I'm sure a new patch for .6 would be released similarly. 11.0 is not an MTS.


Edit: Just checked the release notes of the latest .6; 11.6.7. According there the issue still persists and they recommend upgrading to 11.12.1. See if that's a possibility. As an alternative, perhaps the issue only persists in a more recent version of 11.6, so perhaps updating to 11.6.3 or so would fix your issue if 11.12.1 is too new.

"TypeError: t is not a function" is a global mendix problem with the Windows webView affecting in some way all Mendix versions. For more info see this Support article. Currently only version with a propper fix is 11.12.1, but fixes for 10.24 and 11.6 are on the way.
