As far as I’m aware there is no built-in way to prevent Revit from switching to the modify tab. However, it may be possible to create a workaround. But, it would be difficult to implement what I have in mind and I would not recommend it either.
As for toggling panels of a ribbon. It should possible to disable the tabs/panels/buttons of anything in the ribbon through the AdWindows.dll. However, I’m not sure if such a use case is officially supported. I’ve done something similar that will hide and disable one of my tabs when I’m not in a FamilyDocument.
you are unlucky, I uninstalled the previous version and installed the latest from 2 days ago and it worked like a charm with so many improvements.
You may want to file an issue report on their github accompanied with your revit journal file that will show the devs a bit more what is happening that makes it crashing
regarding your first question, isn’t it what you are trying to achieve?
Oh, yes! Thank you @Jean-Marc i didn´t know that. Would be great if we could controle that with the API but I´m afraid it´s not possible. So maybe working with an untoggled panel will be the better solution…
