Renaming device entity/core entity, HASSIO not loading after renaming

Hello guys,

Last night I was renaming my xiaomi sensors in HASSIO. After the last home assistant update the only way to rename devices was through the device entity file.
I forgot to put " " for one name and when I restared the GUI will not load again…

My question is: How can I access the file and rename it with " " ?

I have Samba installed and can access shared, confic, SSL folders etc. but not the STORAGE folder where the file is placed…

Thanks !
