If using GNU find, then you can delete it by the inode.
ls -lid -- *env*.env*
The number in the first column is the inode. Note what it is for the file that you actually want should others with the string env in the filename exist.
find . -inum <inode> -exec rm -f {} \;
Replace <inode> with the actual inode number. You can remove the -exec part so that you know that it is returning the file that you want before deleting it.
You can also use:
find . -inum <inode> -delete
I sometimes use the -exec bit out of habit but either one works.
