Hi there! would you mind checking the browser’s console to see if you have any javascript errors when you get the blank page?
Also, you might want to try disabling the plugins you have one by one to see if there are any potential conflicts.
Sorry for the inconvenience. And your help figuring out the issue is appreciated.
I have no idea what this means!, but this is what I get:

I just deactivated the Gutenberg plug-in and it fixed the problem: no more white screen and I can edit fine 🙁 Which implies its the latest update eh?
I don’t want to leave it deactivated, but will have to temporarily so I can work on my posts.
There’s two issues here, the first one is just a warning and is tracked here https://github.com/WordPress/gutenberg/issues/22193
The second one is the blocking issue:

That said, it’s very hard for me to know where the issue comes from that, I need to know more about how to reproduce, did you try disabling your other plugins to see if there’s anyone causing conflicts.
So I re-enabled the Gutenberg and disabled all other plug ins and the editor would work again. I am currently going through them one by one to find the culprit, so it might take sometime. But you were right, there is a conflict. I’ll post later which one, when I find it.
Its Yoast SEO!! I tried it first with several other plug-ins activated and then afterward with just YOAST SEO and the Gutenberg plug-in activated and I get the white screen when I try to edit.
Ohh! it seems related to this issue https://github.com/WordPress/gutenberg/issues/25045
We’re actively working on it and hopefully, we’ll be releasing a patch version soon.
I am having the same problems and thought it might be some Gutenberg block add-ins that were causing the problem, since not only couldn’t I edit anything in block editor mode but the pages were not rendering these custom blocks anymore. I tried deactivating Gutenberg Post Blocks and Advanced Gutenberg but to no avail. But I also have Yoast SEO, so this is the likely culprit. I have downgraded to 8.8.0 in the meantime and am looking forward to the patch.
Ok, thank you very much. I will follow that now. Thank you very much for your patience and help.
We just released a patch version 8.9.1. Let me know if fixes your issues.
Hi Riad, updated to 8.9.1 and all looks good! I am able to edit, NO white screen and can’t see any problems, everything seems in order so far (y) Thank you.
Same here. I’m still having trouble with another plug-in, but I think that’s on them. I’m able to edit and the white screen is gone. Thanks for the update.
