Hello, please don't create duplicate topics, you have already made a similar topic.It would be better to keep both the questions in the same topic rather than making two.
But I think these two are separate from each other.
One is that the error occurs depending on the location,
The other is that I get an error when I change the variable name.
That's why I created a separate topic.
I believe that I have a fix for this issue. I have set up a test server where you can import your projects to test the fix. Please let me know whether or not it works for you.
I confirm that it is the same in Polish. When changing the name of a variable, all the variables that were renamed crash. In this case, refreshing the browser does not help. You have to manually reselect the name in each variable block.
