Why doesn't Whatsapp start?

I have a Dell laptop (Latitude e6430) with Windows 10 pro 64x. I have Whatsapp installed here and Whatsapp doesn't start up every time I take my laptop out of sleep mode. I have already reinstalled WhatsApp, restarted my computer, deleted the cache, but in the end it only works once and then again no longer. After starting the app for the second time, it loads a little and after that nothing happens. What can I do?

Use Opera, which has Instagram, Whatsapp, Twitter links integrated in the sidebar.

Missing authorization for the app?

Another browser e.g. Opera (he has it with him)?

No admin rights?

Internet connection?

I use the installed app and not whatsapp web

The app has all the permissions it needs and i use the app and not whatsapp web. The internet connection is stable

Then it would be worth considering. Whether you download this via the installed APK on your computer, or whether you simply use Opera.

If I have misunderstood something again, then I'm sorry, just answer simply to the subject area that you have selected above.

I really liked to organize my storage and only install the most necessary apps, so I would be very reluctant to download another browser

I have now deleted WhatsApp and all the files for it (deleting everything is essential here) and installed WhatsApp from the MS Store instead of the official site. The whole thing loads a little longer with each start and the picture of the shortcut leaves a lot to be desired, but everything works again
