Repro:
Just open KGEN/test/parse-mojo/statements.mojo on VSCode with the lsp enabled. Then the following crash happens in the parser. It seems not to be caused by the LSP.
Assertion failed: (detail::isPresent(Val) && "dyn_cast on a non-existent value"), function dyn_cast, file Casting.h, line 650.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
