> Thanks for your suggestion. I put “JULIA\_NUM\_PRECOMPILE\_TASKS = 1” into the global environment variables, restarted the machine and tried “julia:start REPL”. Results are mixed: on my Ryzen 7 5800H notebook, language server did compile, and now I have a REPL in VSCode on that machine. I tried some julia standard library method calls in VSCode julia REPL, julia seems to work. However some more serious testing of stability has to be done. on my Ryzen 1700 desktop, behavior did not change. Tr…

In short: I have a Ryzen setup and had similar problems (including crashing Firefox), limiting the precompilation threads solved the problem, but slowed package installation etc.  
Weirdly for me, I started to see similar crashes in Julia 1.7.3 and on my other PC with an Intel processor, so also cannot say for sure that this mitigates it.  
But you can try if it helps.
