I recently (13 May 2022) updated Windows 10 with the latest updates and immediately after that I've started experiencing problems with the alert viewer. The viewer appears but as a white block without any content in it, I can move the block and dismiss it but I can't click on anything in it. if I leave the block on the screen it hangs and shows that the application is not responding. I have replicated this behavior twice now and I can't figure out how else to manage the alert messages to allow or deny apps from connecting to the internet.
I've set my firewall to let me decide whenever an application needs to connect to the internet and with the alert viewer hanging I can't perform this task. Is there any other place I can manage this task without changing my setting in the firewall.
I've tried updating Mcafee and reinstalling Mcafee but it does not help. also tried updating Java but that didn't help either.

I have exactly the same problem after the windows update. There is a task Mcafee ChromiumContaineredelegate.exe that gets triggered and it chews up 100% of my CPU and bout 5mb of disk then hangs.
The only way round it for now is to disable the Firewall for 15mins to enable the required executable to run.
I'm having the same problem, it happened after that latest window update. Chromium container delegate or whatever eats my cpu and memory. While the alert viewer only shows a white box and after a while shows code text. Can't add the file because the image file is to big. But says - @charset "UTF-8";[ng\cloak],[ng-cloak],[data-ng-cloak],[x-ng-cloak], ng-cloak,. x-ng-cloak,. ng-hide:not(ng-hide-animate){display:none !important;} ng\:form{display:block;} .ng-animate-shim{visibility:hidden;} .ng-anchor{position:absolute} alertviewer-app
Not OP, but same issue here.
I am having the exact same message in the screenshot.
it is blocking sites because I can't click allow.
Operating System = Windows 10 Enterprise, 64 BIT, Version 21H2, OS Build 19044.1706, feature Experience Pack 120.2212.4170.0
Mcafee = Total Protection, Version 16.0, Release Name 16.0 R46
screenprint attached =
In addition then the Mcafee "Chromium Container Delegate" task/service takes up all the system resources CPU, Memory and Disk for a while +/- 1 hour then it releases it but the alert viewer still does not work.
I'm not going to add to the bandwidth except for saying this too has happened to me after a recent Win10 upgrade all of the screen shots show exactly the same screens that are happening to me & an upto date current subscription of Total Protection - please fix this as soon as possible - turning of my firewall is not an option
Exact same problem after latest windows 10 update. Same blank white text box at first, after a bit with the same text in the white box. I tried resetting the Alert settings to see if saving the changes would revert the alert viewer back to normal operation, but it does not, nor does restarting Windows ... So yes, please fix this ASAP.
