Gutenberg hangs up and much more

Hi,

I don’t even know where to start. I’m really desperate with the Gutenberg editor. Constantly strange behavior from the editor.

1. At the moment I have the problem that I can no longer save pages. The Cpu load on my server is at 99% and in the console I get the following error messages:

Uncaught Error: Minified React error #327; visit https://reactjs.org/docs/error-decoder.html?invariant=327 for the full message or use the non-minified dev environment for full errors and additional helpful warnings.

2. I often get the error messages:

Block Contains unexpected or invalid content.

3.if i want to move blocks to certain positions, it is a gamble that they will end up at the position.

4.and I have to search regularly for the add block plus sign because it is not displayed after each block.

It’s really frustrating and I invest a lot of time every day and give Gutenberg a new chance every day but it’s very hard for me now and I’m thinking of using another page builder again. That would be a pity.

best regards
