Messenger will not work

I have messenger installed on my IPhone and my laptop and it works just fine, however on my desktop it will not.
Here is what is going on:
I click on Messenger and it opens like normal and then i click on the Camera to start the conversation, but it will never open the next window it just says "loading"

now i click on the 3 dots and select "something is wrong"

Then i select other and then technical issue

after that it will work, but only for this session. after i close messenger i have to do all that again to get it going again
I can do that, if i want to make the call. but if someone calls me it will take to long and then i miss the call.
any one know how to fix that?
Thanks
Sven
