LogSeq Stucks during the First Launch after installed in ChromeOS Flex

LogSeq Stucks during the First Launch after being installed in ChromeOS Flex.

I installed the ChromeOS Flex on my old Lenovo G460 today. And all running fine, so I installed LibreOffice by Flatpak. LibreOffice can be used and can be used normally.

Then I installed LogSeq using Flatpak. The installation has been completed without any error message.
However, after clicking the icon of LogSeq, it keeps loading and got stuck during the first launch of Logseq.

Anyone here could advise me on how to fix this?

Thanks
