After Effects' preview stays black all the time

Hello.

After Effects on a colleague's laptop stays with a completely black preview of the composition all the time. I've worked with After Effects for 9 years and I've never encountered this problem before. I tried so many things, but the preview of the composition just stays black. Nothing shows up. The laptop is with the latest version of AE. I also downloaded an older version from the creative cloud, but it's the same problem. When you create a new composition the preview is just black and whatever you place inside the composition it remains black.

After Effects worked fine the previous week, but he said after the weekend this problem occurred. I tried so many things I found by googling the problem, but nothing works so far. Any idea what the heck is going on?

Thank you in advance.

Does the latop have an Intel GPU enabled? We've seen reports that some Intel drivers are causing issues when there are also NVIDIA drivers installed.
 
Here are some steps to try:
 
• Close After Effects
• Go to the Device Manager (Run >> devmgmt.msc)
• Select Display Adapter, Right click on  the "Intel UHD graphic card".
• Select "Update Driver"
• Select "Browse my Computer"
• Select "Let me Pick from a list of available drivers on my Computer".
• Select "Microsoft Display Adapter".
•  Launch After Effects.
 
Let us know.

We disabled the intel GPU and it fixed the problem!
Thank you!
