Installation path not good

Hi, 

installed LRc on an external SSD. Now the SSD is broken so i wanted to install the programm on my normal Mac Air M1 directly. 

I changed the installing Path back to /users/"MyUsername"/applications. 

When i click installing, the paranmerter loads a few seconds, shows 99% and then finishs. Without anything happening. After it, i can click "installing" again, with the exact same result.

Can anyone help?

Thank you!!!
