Lately I’ve been experiencing that preview is stuck on “Host is loading project…”. This for instance: [https://github.com/bolav/fuse-jsbundleimagesource](https://github.com/bolav/fuse-jsbundleimagesource) With this command: `fuse preview BundleImageList.unoproj` ---

Same here when trying to `preview` just the default code after creating a new project. Fuse version 0.11.0 (build 6183) Uno version 0.26.9-OSX (build 1951) ---

It’s not necessarily Android related. Happens with Local Preview as well. ---

When I ctrl+c a stuck preview I get this, although I think it’s not really useful: ```auto Build completed in 7.51 seconds. 0 Warning(s) 0 Error(s) Build ended GL_VERSION: 2.1 INTEL-10.14.58 GL_VENDOR: Intel Inc.

Hi guys, Bolav, I am unable to reproduce the problem with the project you linked. The rest of you experiencing this problem, can you please help debugging by typing ```auto fuse host-preview ``` in the project folder. This should give a more detailed error message for this kind of error. Thanks! ---

For those doing `fuse host-preview` as mentioned above, the full command you need is `fuse host-preview --compile-only YourProject.unoproj`. Note that if this command succeeds, it will output the bytecode of your project, which you might not want to post here. You can just remove everything in the `Dumping stringified bytecode` block of the output before pasting. ---

Update: apparently I had messed up the unoproj file (ux file inclusion missing), but the fact is that the “Host is loading project” problem was occuring back when I had only “_\*" in the included files section. After adding "_.ux:UX” to the includes, the fuse host-preview compiles without errors, but the problem remains: preview stuck at “Host is loading project”. ---

Hi Costin, I just wanted to let you know that I’ve reproduced the problem with your project, even after fixing the `.unoproj`. We’ve made a top priority ticket to investigate this. We’ll keep you posted here as soon as we know more. ---

Hey, Pinpointed the issue to the video tag. An app with the following content would hang in that state. The video file in question used to load properly on older builds. ```auto ``` Even more specific, the app blocks if AutoPlay is present. Without it, the video preview shows fine. ---
