Help please with custom integration error

Hello!
I use custom integration which is not supported by its author.
And after update HA to 2024.06 it raises an error

Detected blocking call to open with args ('/usr/local/lib/python3.12/site-packages/pytz/zoneinfo/Africa/Abidjan', 'rb') inside the event loop by custom integration 'lkcomu_interrao' at 
custom_components/lkcomu_interrao/_util.py, 
line 61: return __import__("inter_rao_energosbyt.api." + type_, globals(), locals(), ("API",)).API (offender: /usr/local/lib/python3.12/site-packages/pytz/__init__.py, line 108: return open(filename, 'rb')),
