This may not be a long-term solution for you. The issue you've described is a known problem and it has been reported on Github.
I'm not sure what I would do in such a case but it's definitely worth reaching out to the LastPass support team and the Magento 2 development services team, to see if they can provide a fix or a more permanent solution. In the meantime, you can also try using a different browser or disabling the LastPass extension only when accessing the Magento 2 admin. Keep in mind that when working with an eCommerce platform like Magento, it's always a good idea to have a team of experts in Magento 2 development services to help you troubleshoot and optimize your platform.
Hi there! Thank you for sharing your experience with the Magento 2 Admin loading issues with the LastPass extension on Chrome. It's great that you identified the root cause of the problem and found a solution by disabling the extension. Hopefully, the LastPass extension developers will notice this issue and work towards a resolution.
I also use Magento development services for developing my e-commerce business. Thanks again for sharing!
