Well… I finally decided that doesn’t matter how big my screen is, I am going to recreate it. So I then created a brand new project, added a new screen & then manually added 150+ components in it. Everything worked fine, until I added a Web-Viewer. I have an HTML file in my app’s files/assets, whose task is to check whether an entered email is in a valid format. The moment I set the web-viewer’s URL to my local file (`verifyemail.html`), and opened the screen in Thunkable Live, my app crashed. I then removed the URL, and added an actual URL (eg. [https://www.bing.com](https://www.bing.com)), and found that now it doesn’t crash. Then I added the local URL again, and it again crashed. Since all these tests were done in a new test app, I tried the same thing on my original project (removing the local URL from the web-viewer) and found out that my original app doesn’t crash. It works very smoothly. So turns out, all along the problem was not with the `navigate to` block, but with the web-viewer with the URL set to a local file. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/9/f/9fb96bf2f2e74ab4846ab36e992048f561c7b47a.png) ---

But now, what should I do with the local file? I need to use both the files, because the only way I can check if the email is valid or not is through the first file, `verifyemail.html`. The second file’s task is to encrypt text, `encodedata.html`. I send the `encodedata` file some text I need to encode through the web-viewer POST message method, and then receive the encoded data through the `received message` event; and then use the encrypted data further. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/8/a81e66602eb8c607b25871290fb78a54f034dda2.png) ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/e/5/e59e42f6c115f2ab338c5dc5dadbf60765f8ad92.png) * * * The files worked all the time through the web-viewer. Everytime I would successfully get the email validation & the encoded data. The problem is, it just crashes my app. Is there any way you could suggest, so not only I could use the local files with the web-viewer, but also prevent my app from crashing? Thanks a lot! 😀 ---

@jared If I am right I remember you also worked with local HTML files in one of your apps - Do you have any advice on this? (refer to the last post) Thanks! ---

Thanks for sharing this finding! If you open verifyemail.html in a normal web browser, does it look OK? If you get a sample HTML file from the internet and try to display that in your project, does it cause the same behavior? ---

So you first get the data and can see it but then the app crashes? ---

My app is also crashing sometimes… I don’t know why ---

Hi, @jane @jared! First off, sorry for the delay - I’ve been unable to reply… I tested all the points, and found out the following conclusions - - I hosted that HTML file on my website (so it would be as `https://xyz.com/verifyemail.html`) and put its URL into the web-viewer in order to test it to see if it worked. - The **web-viewer** doesn’t work & crashes the app when **set to invisible**. - Both the online hosted HTML file & locally stored file showed crashes when they were set to a web-viewer which was invisible. They both started working when I added some height to the web-viewer. **Conclusion:** The main problem lied in the invisible web-viewer. If a web-viewer is set to invisible/height=0px, then it would crash your app. If you really want to hide it, you can set it’s height to 1px, so it won’t be visible. So, I did the same as above, and it worked. Thanks! ---

This is what I did for the web viewer to work (DnD UI) to make it work. It never worked good if set to **invisible**. ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/d/1deb050e7edbc9c99ddb250925f552ffe9da233d.png) ---

Resizing is ok, but how to bring previous size (full container)? ---

In DnD UI, there is no auto sizing therefore there is no `full container`. ---

Ok solved it by setting set WebViewer URL to BLANK (pink, empty field) set column with WebViewer to false ---
