Project won't open with out of memory error

Please can someone from Unity help me - I am frantic right now and feel like the last 6 months of my life have been destroyed in front of my face.

Since performing a system restore (due to a power-cut during a windows update install) back to 10th December, I cannot open my most recent Unity project. I get a fatal “out of memory” error, as shown below

Assuming the “B” in the trying to allocate line is “bytes”, that allocation number is crazy - my entire project folder is only 160MB and my machine has 8 GB memory, so the entire thing should fit into memory easily. I have no idea what is suddenly causing this crazy allocation, and the error is thrown INSTANTLY upon trying to open the project.

Deleting the “library” folder from the project files allows the project to be opened, but then I get dozens of File Serialisation errors and all the scenes and prefabs are empty.

I’ve submitted a crash report but heard nothing back on it yet

This means that your PC is reserving the 8 gigabytes of data for system functions. Try deleting some data or moving it to a flash drive.

So what did you do to fix this?? My project wont open now because of this problem. How can i open my project to fix this??

  1. On a disk with the system must be at least 20 gigabytes of free space

2.clear cache C:\Users\Степан\AppData\LocalLow\Unity\Caches\GiCache

3.Restart the computer.
