Current Behavior / Expected Behavior

Importing apps from DNN to test in Oqtane. Some work with no issues, other report this:

Error: System.Exception: Error: Can't compile 'AppCode.dll' in AppCode. Details are logged into insights. Bad IL format. The format of the file ' .... \App_Data\2sxc.bin\App-00006-AppCode-5c98a772de834cf2f6cbaba95a058d43347c40224e3ac673b0d60a04183c20b8.dll' is invalid. at ToSic.Sxc.Razor.RazorCompiler.FindViewAsync(ActionContext actionContext, String partialName, IApp app, HotBuildSpec spec) at ToSic.Sxc.Razor.RazorCompiler.CompileView(String partialName, Action1 configure, IApp app, HotBuildSpec spec) at ToSic.Sxc.Razor.RazorRenderer.RenderToStringAsync[TModel](String templatePath, TModel model, Action1 configure, IApp app, HotBuildSpec hotBuildSpec) at ToSic.Sxc.Razor.RazorEngine.RenderTask(RenderSpecs specs)

@tvatavuk any ideas?

Is there a chance that two compilers try to create the file at the same time, and refuse to overwrite a 0-byte file or something?

Deleted the files in the folder, restarted the server, same output. One app generates the files and the app runs, the other generates the errors.
