Good day

I need help please when starting up my steam I get a "Something went wrong" message with error Ref Store and then numbers and Loading chunk 8970 failed and in brackets "missing https/:store.fastly.steamstatic.com/public/javascript/application/store/............

So it does not want to show any preview video of games and I also can't buy any new games.

I did try to run as administrator only work with start up of steam, did clear my Cache, did uninstall steam and re-installed, did try the end task manager and now I am getting frustrated.

Any thing more I can do?
