Batch file infinite loop with pyuic5

I don't get why first script infinite loops while second doesn't.

Googled for this problem, but since I'm nowhere near to guess what's cause of this, I'm asking here what's wrong with first script.

Got results from PyCharm Terminal, but results are still same on cmd.

1st

cd %~dp0
for %%f in (./*.ui) do pyuic5 ./%%f -o ./%%~nf.py

Z:\github\python-macro-practice\Qt_UI>cd Z:\github\python-macro-practice\Qt_UI\ 

Z:\github\python-macro-practice\Qt_UI>for %f in (./*.ui) do pyuic5 ./%f -o ./%~nf.py 

Z:\github\python-macro-practice\Qt_UI>pyuic5 ./methodItem.ui -o ./methodItem.py 

Z:\github\python-macro-practice\Qt_UI>cd Z:\github\python-macro-practice\Qt_UI\ 

Z:\github\python-macro-practice\Qt_UI>for %f in (./*.ui) do pyuic5 ./%f -o ./%~nf.py
