Error witho Bio.Alphabet

[GM110Z]

Hello

I have successfully used FlaGs2 before but now that I have changed computer and re-installed every dependency, it throw an error about Bio.Alphabet (see below). Any suggestions?

Traceback (most recent call last):

ImportError: Bio.Alphabet has been removed from Biopython. In many cases, the alphabet can simply be ignored and removed from scripts. In a few cases, you may need to specify the molecule_type as an annotation on a SeqRecord for your script to work correctly. Please see https://biopython.org/wiki/Alphabet for more information.
