Edit: The below "solution" just seems to have been a coincidence. Issue returned. Now I'm looking into opencl.dll being corrupted.

Since I've found multiple threads on this issue, I'm going to cross post a bit, just in case this solution also works for others...

I suddenly ran into this (or very similar problem on my Win10x64). Pressing "Launch" the eso.exe simply freezes when it should start showing the developer logos/intros. Finally decided to troubleshoot a bit, and found the following entries in my eventlogs, at the time of pressing "Launch".
In Application log:

Activation of app 436337Illusions.com.MediaBrowser_77hd5e1v1hqs4!App failed with error: No applicable app licenses found. See the Microsoft-Windows-TWinUI/Operational log for additional information.

In System log:

Unable to start a DCOM Server: App.AppXhyg4cy62s7gghctkf48aq5csrzdn44mk.mca as Unavailable/Unavailable. The error:
"3236560897"
Happened while starting this command:
"C:\WINDOWS\system32\backgroundTaskHost.exe" -ServerName:App.AppX9c2je2s29fsgzvc6339srtj1ypxtqfe5.mca

I then went on to uninstall the Emby (formly known as MediaBrowser) app, and then tried again, and it no longer failed. I haven't not done any thorough testing, so the issue could come back, however, previously only a restart would fix the issue (most of the times). This time the issue was fixed right after removing Emby.

My hypothesis is that eso.exe was trying to use the app to playback the intro video, and the app then failed.

I read a comment from another poster (can't remember which post), where they mentioned their Logitech keyboard being the cause. I believe I can confirm this. Issue was there using my Loitech G110 keyboard, but disappeared the moment I connected my Microsoft ergonomic (not good for gaming) keyboard.

Tried installing an older version of the Logitech Gaming Peripheral software (some people on Logitech forums mentioned that they resolved it that way, but this didn't resolve it for me. Now using a Corsair keyboard and haven't experienced the issues since.
