After upgraded magento 2.4.5, when I login dashboard, It always got error: A technical problem with the server created an error. Try again to continue what you were doing. If the problem persists, try again later. I would be logout after refresh page.
I have to try many times and I can login successfully one time.
there isn’t exception log in magento, but I checked nginx error log:

my server is nginx/1.22.1, I tested it on my local machina with apache, all work well.
I set memory_limit = 20G,
max_execution_time = 86400
