I cannot precompile my julia 1.10.6 LanuageServer in my new win11. Could you tell me what the problem is? I tried reinstalling Julia, but that didn’t solve it.

Run in julia REPL

```julia-auto
using Pkg
Pkg.precompile()
Precompiling project...
   Progress [==========================] 49/50
   LanuageServer

```

**precompile LanguageServer very long time**

versioninfo is as follows

```julia-auto

**precompile LanguageServer** has two hours, but not ok.
