I checked your resource usage graphs (the ones you can also see in the control panel) and I see your daily CPU usage graph is extremely high. In the hour or so your account was active generated, it may have generated enough CPU usage that it went over the daily limit in that short period of time.
You could try to enable “I’m under attack” mode in Cloudflare. Doing so will prevent most bots from accessing your website. And unlike Elementor’s maintenance mode, Cloudflare will prevent any PHP code from being executed, which saves you some CPU power, and may allow you to access your website long enough to try to reduce the CPU consumption.
