Hey,
not sure if it is the same issue, but I have similar setup (Ryzen + Windows) and about 1-2 weeks ago started seeing Julia struggling and crashing taking the whole VSCode down (and sometimes crashing my Firefox also). However in my case the same behavior is also present on i7-8700k machine.
So my best guess was that it is an iteration of an older issue (link to github issue is in the thread above).
You can try to add to your environment this variable:
JULIA_NUM_PRECOMPILE_TASKS = NUMBER
where number should be less then the number of cores in your CPU.
At least that is how they mitigated the issue earlier. For me it reduced the frequency of crashes, only setting it to 1 completely fixed it.
Let us know if this helps your case or not.
