Microsoft Edge closes immediately upon opening. I've tried many fixes none work.

This worked for me, though reading down through all the subsequent comments where people are saying that it didn't work for them has me concerned.

Microsoft need to address this problem. We've all had overnight updates and we've all had Edge crashes thereafter. What's the common factor? Microsoft.

Check task manager to make sure no remnants of Edge are still running (locking the folder); also, you may need admin rights to modify the folder. Someone with more technical knowledge might be able to address the greyed out issue.

Thank you! this was the only "fix" that has worked for me!

Modify option is grayed out.

The folder can be located as follows:

Note - everywhere you see "username" this should reflect your local pc account

1. Window+R
2. run %localappdata% ; this opens file explorer to the C:\Users*username*\AppData\Local folder
3. navigate to the microsoft folder; C:\Users*username*\AppData\Local\Microsoft
4. navigate to the Edge folder; C:\Users*username*\AppData\Local\Microsoft\Edge
5. navigate to the "user Date" folder; C:\Users*username*\AppData\Local\Microsoft\Edge\User Data
6. find the Default folder and rename this to original-folder;
7. then restart Edge

This will reset Edge to a default new profile startup; if your information is syncd to Microsoft; the shortcuts and links and passwords will be restored from the Internet based on the last time it was syncd up.

This was the only solution for me that worked.

How did I discover this:

(1) in my default normal profile Edge continuously shutdown on startup; nothing worked

(1-a) - was unable to launch Edge and try any of the recommended solutions

(1-b) - was unable to initiate a Repair from Settings and Edge under Apps - yes, it did download and re-install but on launch shut down

(1-c) - I verified via TaskManager that no Edge or Edge Related Apps were running during the re-install/Repair

(2) Verified Edge worked fine on the PC via another Profile on the PC

(3) Researched the Internet (using another browser) and after 6 hours of searching found one source that stepped through the solutions; https://youtu.be/oTVTviAtYZ8?si=lCYb0eCmHld36spe  In the video, the second solution (beyond Repair) was the key that worked - at least in my case. This is outlined above.

Beyond this, Please BeCareful if youve never ever had to resolve issues using Powershell or unfamiliar with command oriented solutions or file manipluation.

Fortunately, from DOS 2.1 forward I've got some historical experience.

My logic is start simple and work into the complex as needed.

Best of Luck.
