I was installing Plugin on qgis 3.10 ltr when installation precedure finished, qgis closed without any error message! I opened qgis again after that when I did select this plugin in QGIS plugins list, QGIS closed immediately same as before

@Navid61 not sure what the problem could be.
I was not able to reproduce with QGIS 3.10.13 LTR on Windows 10.

If you are on Linux the problem might be missing python3-shapely or matplotlib on your system.
Although in that case no crash should happen and you should get an error message.

Apart from that you could also try to disable all other plugins and check if it works then, maybe there's another plugin that interferes.

I'd same problem when I did upgrade to 3.16.2, I installed python3-shapely by sudo apt-get install python3-shapely and I did remove all plugins but It didn't fix, another issue I should mension, when I want install that, It will close QGIS without any error message
