Dear HelderdosSantos
Good day!
I really appreciate your feedback, which has really given us some insight into this issue.
I would like to make a summary on this issue to find the information easily. This will also help other community members t o find solution much easier of they come across the same situation:
Issue Description:
The list cannot work properly and the page became all white
Environment:
SharePoint List
Multiple browsers
Suggestion:
This phenomenon may be related to the performance of a specific List. Check whether a column with a large amount of data exists and adjust it. If you are unable to fix the list, you can also contact the administrator user, which will further connect you to Microsoft Support, who has permission to remotely assist you with fixing the issue: How do I find my Microsoft 365 admin? - Microsoft Support & Get support - Microsoft 365 admin | Microsoft Learn
I think it is also necessary to check whether this problem occurs in multiple Lists first to further confirm whether this situation conforms to the above description.
Many thanks to HelderdosSantos for the repair suggestions! I wish you all the best!
Sincerely,
Tin | Microsoft Community Moderator
