"Ran out of memory allocating x bytes with alignment 0" Error when saving-loading

Hi! I just wanted to add to this issue because I got here trough google and maybe some other dork like me can use this. In my case the issue was caused by not having the virtual memory enabled in Windows. I set it to Automatically manage paging file size for all drives and the issue was gone.

I am having the same problem and I have been trying for days to find a sollution. I read from another member that you should do exactly the opposite, meaning that you have to define manually the size of virtual memory and not let windows decide automaticaly. In my case the default setting was to automaticaly define the size so I changed it manually (I have 32GB of RAM). The problem was not solved. I tried to change it again like you suggest , but the problem is still there.
Here are the last lines of the log file.

Does it matter that the project is in C: and I am packaging in the E: drive?
Also, my free space in C: is kinda limited (about 40GB). Does this matter?
Any help would be highly appreciated.
