Changing key signature with the Change Instruments function and transposing instruments lead to a crash under certain circumstances
Version 3.6.2 / Windows 10

I don't know what happens internally, the unique trigger (if there is one?), but I can reproduce from scratch. First of all, there are a number of necessary conditions: at least 2 instruments, with parts.
And it doesn't matter if we are in pitch concert or not.
There seems to be a mishmash with Instruments change, transposing instruments, and key signatures, except however from what I can see at the moment, if the instrument that has been changed is not transposing, for example piano or flute.
Steps (example for this test file) : flute and clarinett.mscz
- Create a score for 2 flutes, 4 measures
- Generate parts
- Make an instrument change, from the second flute, to a clarinet.
- Select the first measure (first or second flute, no matter)
- Click the key signature in A (3 sharps)
Result : crash
