Hello! I don't want to generalize but as far as I know, your I-765 will be denied if you have a pending green card application based on asylum.
Keep in mind that as an asylee, you do not need the EAD to verify employment (but only as ID documentation). the EAD is not necessary even as as asylee only. The department of justice has ample resources online that explain why the EAD is not a necessary document for asylees.
Either way, I wouldn't worry at all!
it makes no sense to accept your I-765 if you'll be getting your green card soon!
Did they say why it was denied?
