Trouble opening EDE projects on Windows

Hello I'm having some issues opening projects after restarting emacs. 
EDE works just fine
before restarting emacs. So any project that I created during the 
current session works as it
should. When I try to open a file again then I get the following backtrace:

Debugger entered--Lisp error: (wrong-type-argument arrayp nil)
   child-of-class-p(ede-proj-target-makefile-program ede-target)
   eieio-persistent-validate/fix-slot-value(ede-proj-project :targets 
(list (ede-proj-target-makefile-program "cybi" :name "cybi" :path "" 
:source (quote ("error.c" "lex.c" "main.c" "parse.c" "parser.c")) 
:auxsource (quote ("bool.h" "lex.h" "parse.h" "parser.h")))))
   eieio-persistent-convert-list-to-object((ede-proj-project 
"cybi-project" :file "Project.ede" :name "cybi-project" :targets (list 
(ede-proj-target-makefile-program "cybi" :name "cybi" :path "" :source 
(quote ("error.c" "lex.c" "main.c" "parse.c" "parser.c")) :auxsource 
(quote ("bool.h" "lex.h" "parse.h" "parser.h")))) 
:configuration-variables (quote (("debug" ("CFLAGS" . "-Werror -Wall 
-Wextra -std=c89 -pedantic-errors -Wmissing-prototypes 
-Wstrict-prototypes -Wold-style-definition -g"))))))
eieio-persistent-read("c:/msys64/home/usefulProgrammer/src/yig/cybi/Project.ede" 
ede-proj-project)
   ede-proj-load("c:/msys64/home/usefulProgrammer/src/yig/cybi/")
   #[(this dir) "\303\304\"\204

And if I call M-x customize-project instead I get this backtrace:

Debugger entered--Lisp error: (wrong-type-argument (or eieio-object-p 
class-p) nil)
   signal(wrong-type-argument ((or eieio-object-p class-p) nil))
   eieio-oref(nil local-variables)
   customize-project()
   call-interactively(customize-project record nil)
   command-execute(customize-project record)
   execute-extended-command(nil "customize-project")
   call-interactively(execute-extended-command nil nil)


I have tried doing the process without my .emacs file so I know that 
it's not a configuration error. Hope I can get some
help resolving this. I believe it to be a bug. I also tried it with 
Emacs 24.4 and it was the same.

Cheers!
