Conda installation conflict

[ASUQ]

While running

PanACoTA prepare --norefseq --min 0 --max 1 -o 1-prepare --cutn 125

after installing it by conda with the new environment, I got an error message

~/panacota/lib/python3.7/site-packages/python_utils/converters.py", line 89
    if match := regexp.search(input_):
              ^
SyntaxError: invalid syntax

This is probably because the python version that was installed was v3.7.12 but not newer than v3.8.
(walrus operator is available in python >= 3.8)

When I tried to update the python version with

mamba install -p <path to the environment> "python>=3.8"

I got

Also when I tried to update the python version with conda,

conda install -p <path to the envirionment> "python>=3.8"

I got
