System error when using precompiled packages

I’ve been using the precompiled packages feature in VSCode without trouble for 2 months. Without it programming is impossibly slow, since startup time is many minutes.

Starting this last week at random intervals the error below happens. The code runs fine using the sysimage for a while and then it stops working. It looks like the file is being corrupted, or maybe the registry is being corrupted or maybe both.

Once this happens the only way I’ve found to fix it is to blow away the sysimage and registry and rerun the package compiler. This takes a very long time. Has anybody else encountered this error?
