Browser Crashes When Uploading large files

Which Umbraco version are you using? (Please write the exact version, example: 10.1.0)

14.3.1

Bug summary

I’m encountering an issue when uploading a PPTX-file in Umbraco. Every time I attempt the upload, the web browser crashes.

I’ve tested this across multiple browsers - Chrome, Firefox, Edge, and Safari - and the problem persists in all of them. Below is a recording from Chrome for reference.

The PPTX-file opens and functions correctly on my local machine, so the issue appears to be related to Umbraco.

Hi there @martinthogersen!

Firstly, a big thank you for raising this issue. Every piece of feedback we receive helps us to make Umbraco better.

We really appreciate your patience while we wait for our team to have a look at this but we wanted to let you know that we see this and share with you the plan for what comes next.

• We'll assess whether this issue relates to something that has already been fixed in a later version of the release that it has been raised for.
• If it's a bug, is it related to a release that we are actively supporting or is it related to a release that's in the end-of-life or security-only phase?
• We'll replicate the issue to ensure that the problem is as described.
• We'll decide whether the behavior is an issue or if the behavior is intended.

We wish we could work with everyone directly and assess your issue immediately but we're in the fortunate position of having lots of contributions to work with and only a few humans who are able to do it. We are making progress though and in the meantime, we will keep you in the loop and let you know when we have any questions.

Thanks, from your friendly Umbraco GitHub bot 🤖 🙂

Hey @martinthogersen, would it be possible to supply a file that is not working for you?

[martinthogersen]

@Migaroez Yes, I'd prefer to send the file privately. Would it be okay to use WeTransfer to share it with you?

[Migaroez]

Yup, sounds good. Check your linked-in for details 😉

Can reproduce on 15/dev (15.2)
Got this error

Overwriting the runtime settings as described in https://docs.umbraco.com/umbraco-cms/reference/configuration/runtimesettings fixes the server error, but still causes the browser to crash

All browser crashes show a out of memory exception

Not just with PPTX files but any file above ~57MB (57 still worked, 72 didn't)
