Unexpected exception System.IO.EndOfStreamException: Unable to read beyond the end of the stream.

Question

Hey,

I get this error massage every time I start the editor or while compiling of my scripts. Does anyone know, what that means?

Delete the Package Cache / Burst Cache and reopen project fixed it

For anyone else that comes up with the issue, the solution @Matt-Cranktrain provides in this thread (the link from @lliqNikushev 's reply) worked for me.

Open your project root in your File Explorer, go to Library, and delete "BurstCache". If that doesn't work, try also deleting your "PackageCache".

In other words, delete ../[ProjectRoot]/Library/BurstCache and ../[ProjectRoot]/Library/PackageCache.
