Broke my system how to fix it?

My system is broken as the memory card is tighten and can not be taken out.
I was trying to install a https proxy in conjunction with dietpi.
None of the software is available and dietpi-update or anaother commands is not function.
It has become a ordinary raspbian with dietpi.

If the dietpi software is not working, there is a chance that your SD card is damaged or corrupt.
You really need to get the card out and re-image it. There is no other solution where I can think about.
