Running .bat as prep stopped working

[mkaflowski]

I have that bat:

@echo off

chcp 65001 >nul
echo %PATH% > C:\Users\mkafl\Desktop\sunshine_path.txt
echo %PATH%

echo [1/5] Przełączanie na wewnętrzny wyświetlacz...
DisplaySwitch.exe /internal

echo [2/5] Oczekiwanie 2 sekundy...
timeout /t 2 /nobreak >nul

echo [3/5] Ustawianie głównego urządzenia audio...
powershell -ExecutionPolicy Bypass -NoProfile -File "C:\Users\mkafl\Desktop\primary_audio.ps1"

echo [4/5] Oczekiwanie 5 sekund...
timeout /t 5 /nobreak >nul

echo [5/5] Hibernacja komputera...
shutdown /h

I add it to start/end command and get error.
What it helps is adding:
set PATH=%SystemRoot%\System32;%SystemRoot%;%SystemRoot%\System32\WindowsPowerShell\v1.0;%PATH%
after first line.

Did some Windows update brake with Apollo?
I tried uninstalling and installing Apollo.

Have you tried cmd -c ? Or maybe you system's path config got messed up

I have tried and it opens terminal in new window but gives not found for commands like powershell so it looks like path is not set.
When I use full paths it works.
