How run trepan3k with python 3.9 and above?

[dev590t]

The documentation indicates trepan can run with python 3.9:

trepan3k works with Python version 3.2 and above. However the decompilation features are available for Python versions less than 3.9.

However, I fail to run with python 3.9:

Python 3.9.9 (main, Jan  1 1970, 00:00:01) 
[GCC 10.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Maybe I should disable the decompilation, but I found nothing how do that in the documentation.

3.9.9 works for me if you run from current github sources here and for xdis...

$ trepan3k trepan3k
(/trepan3k:3): <module>
-> 3 import re
(trepan3k) python
trepan3 python shell with locals
Use dbgr(*string*) to issue debugger command: *string*
trepan3k >>> import sys
trepan3k >>> sys.version

My package manager has installed trepan3k 1.2.7 when it try solve the dependency graph. After update pyproject.toml to use trepan3k 1.2.8, trepan run perfectly, thanks
