Since last week I am encountering problems with precompilation - with language server on VSCode and with packages in projects.
Seems to be the same issue as here, although it seems it should have been fixed.
For me, the precompilation becomes stable only when I set the number of processes to 1.
Here is the error I get most frequently:

Did something changed recently that might have brought this problem back? I had not seen it earlier.
