Thanks for it but can you please tell me which version of magento works perfect without errors?

 

I have installed and checked 2.3.2 and 2.3.5 but none of them installed and worked without errors. 

 

I am stuck with this for last 10 days.

 

Please advise me which verison i should install and which verison is error free version.

 

Thanks
