Modern experience stopped working today (7th March 2018)
Glad to hear it - we have made a fix, glad it's working for you. We're working on the issue inside attention views now.
We are having the same issue with content types. They work/open when you use the NEW drop-down in classic experience but in modern, you see "Something went wrong message".
Here's the situation for us and what I found after some troubleshooting.
We have 3 content types (word template, excel template, and powerpoint template) that are able to be selected from the Library New button/icon. All of the content types work properly only when IE 11 is in compatibility mode and the library is in Classic Experience mode. When we are in compatibility mode and the library is in modern mode, only the excel and word content types launch properly - the PPT type throw errors like "this action cannot be performed because Office doesn't recognize the command that was given" Finally, when not in compatibility mode, both Excel and PPT types have the same error mentioned in the previous sentence and the Word content type attempts to create generic document but then throw an error like: Sorry, something went wrong cannot create file.
Okay, so today, only the .potx content type does not work in Modern Mode. All other content types seem to be working in Classic and Modern without Compatibility. In classic mode the .potx content type opens up in PowerPoint (application) which is what is expected. In Modern mode I receive this message:
Do you want to open this file?
Program: Microsoft PowerPoint
Address: https://[our 365 root]/sites/PMO/Doc.aspx?sourcedoc=https://[our 365 root]/sites/[company]/Shared Documents/Corporate_Template.potx&action=edit&mobileredirect=true&RootFolder=/sites/PMO/Shared Documents
Anyway, the Address information above is abnormal to me. I've never seen this previously. Usually, the Address: part of it would say: https://[our 365 root]/sites/[company]/Shared Documents/Corporate_Template.potx without all that other stuff. And, that other stuff is not displayed for the Address information when the word or excel content types are used.

Please open a support case, and let me know through private message if you're having difficulty finding a resolution. This might need a product team fix as well.
Please provide a link to open a support case.
Further testing: It seems that when we open a site in classic view (default setting is classic) the content types are attempting to launch in MSFT Online (web browser) version and not the client application. The server setting and library settings are set to use the client application. So, all content types should open in the Office Application that is applicable. When a new document (content type Word template) is selected the online "create document - enter file name" dialog box is displayed. If you enter a file name, and click OK an "unknown" error occurs.
However, if I visit another site and create a new document (same content type source), it magically works as expected.
If I close the tab for the site that originally did not work and re-open the same site/library the new document from the content type that did not work before now also works! Not sure what is happening there.

Dan, do you have an open support case on this already?
Please send me the details on that over private message.
