I can't run multiple instances of Firefox Portable after updated to v 118 and above

Making moves

I have Firefox Portable version 107 and can still operate multiple profiles (instances) normally at the same time, but for the profiles I have updated to version 118 or higher, I cannot open multiple profiles at the same time anymore (when you try to open another profile from another site). Firefox Portable folder is like opening an additional window for the active profile. The exact settings and bookmarks information belong to the previously active profile).
The latest 118 to 119 are the versions I'm having the error on. I don't know if previous versions had this error or not, but with version 107 it works normally.
