'Bake Runtime' job failed with error code: 3 ('Failed reading Bake Input Lighting file.').

Unity Engine

I keep getting the above error.
Originally I was getting error code 8, but then I cleared the GI cache (this didn’t work) & manually deleted the cache folder (this technically did, since I’m now getting a different error).

I can’t find any info about it through searching the forums and I was hoping for any advice.

Never mind, I just restarted Unity and that worked. I have new problems but this one resolved itself.

Most errors caused from HDD free space used for GI cache

This issue can also be symptom of previous Unity sessions (with older versions of Unity) - there could be some incompatible data in cache. As aliyeredon2 said, clearing GI cache should resolve this issue.
