I’m trying to cap the amount of ram WSL uses. I have this config set:
[wsl2] Memory = 4GB Processors = 1 I know GB is gigabyte, but im trying to limit the amount of memory to 512 megabytes, would it be MB? Or M?
I tried both MB and M, but none of them worked. How do I limit to only 512MB?I only have 3GB of RAM on my computer. I also tried to put 0.5GB in the Memory value, still didn't work.

The release notes for this feature say that 512MB is the correct form. Also, this comment on a related Github issue mentions changing it to 512MB and it working, although the thread is locked, so there's no way to confirm that with a reply in that issue.
512MB should work.
From the Release Notes:
<size> entries must be size followed by unit, for example 8GB or 512MB
