"Importing Asset ""blender could not convert the .blend file to fbx file""" (950132)

Hi. I am using version control, and my teammate imported and used a prefab. However, my console log prints a “missing prefab” error.

I tried importing the asset on my side, and there are 4 versions for this model: .blend, .usdz, gLTF, and GLB.

When I try importing the .blend file, I get a “Blender could not convert the .blend file to fbx file” error message, and “Hold on (Busy…)” for too long. I didn’t have Blender software, so I downloaded it and tried again, but it still didn’t work. I also tried the suggested solution in another forum, “modifying the python script to say 3.0.0 instead of 2.80.0,” but I got this message and couldn’t modify the file: “Failed to save ‘Unity-BlenderToFBX.py’: Insufficient permissions. Select ‘Retry as Admin’ to retry as administrator.”

For the .usdz file, I extracted it, but importing the .usdc file didn’t work properly.

For gLTF and GLB, I saw that I should be downloading the GLTFUtility file, but I also saw a YouTube video stating that it no longer works since 2023. I am not sure about this either.

What should I do to solve this error?

I had modeler send me different file formats so I had everything I needed. Have them send you FBX, OBJ, textures, normal and baked texture maps if required, whatever you need to load it into unity. also if materials are made with shader nodes in blender that all has to be baked and exported as textures for you to add to model or else it will not look right. I had contracted a modeler last year and they were sending me FBX and obj but when I put in unity they didn’t look anything like pictures, so I downloaded blender and started to learn, Now I know what to ask for. will make your life so much easier if they send you FBX and texture files. I don’t even know those other three file formats? sorry can’t be more help.
