[crash]: Cochrane Meta-Analysis crashes jasp

[tomtomme]

JASP Version

0.20 beta

JASP Module

Cochrane Meta-Analyses

What analysis are you seeing the problem on?

all 4

What OS are you seeing the problem on?

Flatpak

Bug Description

As soon as I select a variable to do the meta-analyses jasp is freezing. Sometimes earlier (when result tables are still empty), sometimes later (when already some parts of the results are displayed). In all cases the whole interface is not clickable anymore and the spinning circles in the result window stop spinning.

Expected Behaviour

cochrane should work

Steps to Reproduce

1. open any cochrane analysis
2. select any topic
3. select any variable and wait for the crash popup

yeah, the qml generation is too slow on some OSs unfortunately :( the same issue on my PC

I get sometimes a crash (in debug mode, not in release mode) in the QML Engine self (deep in the Qt code).
I think now I cannot do so much: just ask the user to have a robust machine.
When we upgrade to Qt 6.9, hopefully this version will cope better with such a situation.

[tomtomme]

should we mark the module as "beta" as long as this problem exists? It still exists with 0.95.3 on a very robust machine with 1gbit internet - and we are already using Qt 6.9 I think?

We can add a known issue in the known issue page https://jasp-stats.org/known-issues/, and also we can generate automatically a warning when a Cochrane analysis is started by a user, by adding in our server a known issue json file that is read (if allowed) by all JASP instances.

Good solution!
