I have this error in my vscode after I upgraded to PHP8.
I tried to increase my memory_limit to 4GB or 8GB as this link described.
also, I using the v2.3.14 (last version) of the PHP IntelliSense extension.

    This fixed it for me on PHP 8.0.3:
cd ~/.vscode/extensions/felixfbecker.php-intellisense-2.3.14/
composer update
https://github.com/felixfbecker/php-language-server/issues/779
 
    
    Looks like Felix Becker's Extension is now unmaintained. I fixed the issue by replacing his extension with Damjan Cvetko's PHP IntelliSense, which is a maintained fork of this one: https://marketplace.visualstudio.com/items?itemName=zobo.php-intellisense
 
    
    I also had same issue on WSL2 Ubuntu 20.04.2 LTS trying to use PHP 8.0.2, although my vscode server path is slightly different. Ran the update, reopened vscode and everything is working like it should.
cd ~/.vscode-server/extensions/felixfbecker.php-intellisense-2.3.14/
composer update
 
    
    The problem for me is that I had both extensions installed. Uninstalling felix's solved the issue.
