Crash

source/blender/blenkernel/intern/lib_id.c:117:69: runtime error: member access within null pointer of type 'struct Library'

Full backtrace: P1602

Issue goes away if

- you delete Plane in the main file [linked -- also uses ani_matGlass_v09], save and reopen, ani_matGlass_v09 is then single-user on Cube, make local then works.
or - in the src file you delete those two OSL shader nodes from ani_matGlass_v09:

ok, sorry, see attachment.

Just open "mainFile.blend" and click chain icon (make local) for material ani_matGlass_v09

For me this gives instant crash

I get a crash when I run this in 2.83 as well, yet in the report you said it worked in 2.83. Do you have a sample file that works in 2.83 but not in 2.90?

No, i just recoll that is was ok before at least with this material. But library constantly changes, so seems im wrong regarding 2.83 Its not widely used feature (by me), so i really cant recall when it started to happen //
It was perfectly fine in 2.79 though, i switched moth ago or so

@mont29 this is a very interesting issue. If I start deleting things from the file the issue goes away. That said it is not really a "simple file". I will leave to you to make a call on whether this is an ok "minimal file" or not. You can still delete all but MAani_matGlass_v09 material from the library.blend and still get the crash, roughly:

for m in D.materials:
  if m.name != 'ani_matGlass_v09':
    m.user_clear()
# save, re-open, save

Here are some simplified files:
src.blend
main.blend

Issue goes away if

- you delete Plane in the main file [linked -- also uses ani_matGlass_v09], save and reopen, ani_matGlass_v09 is then single-user on Cube, make local then works.
