Hi @odylalalaaa ,
please check our guide on posting code on the forum and amend your post accordingly.
The error is due to a segmentation fault, which typically indicates there is a bug in your code, e.g. accessing a nullptr or similar. If you could run the code on lxplus using one of the releases with debug symbols the stacktraces might contain more useful information.
Compiling the code with debug symbols and running it through a debugger such as lldb might also help.
Also, to verify that the file can be read correctly in general: can you read and visualize all those branches via TBrowser?
Cheers,
Enrico
