How can it be fixed?

Set Pyyaml==6.0.1, works for me, but maybe choose the closes solution where the above error is fixed.

Workaround:

pip install eth-brownie==1.19.3 --no-deps

in file

.venv/lib/python3.10/site-packages/eth_brownie-1.19.3.dist-info/METADATA

change:

Requires-Dist: pyyaml (==5.4.1)

to

Requires-Dist: pyyaml (==6.0.1)

then complete eth-brownie installation:

pip install eth-brownie==1.19.3 Pyyaml==6.0.1

Ups, Related #1701
