When saving og update posts mye CPU rises to 100%

When saving og update posts mye CPU rises to 100%. This freezes my site. It’s not my server capasity, because this was functioning before. Iv’e deactivited all plugins, but that did not work out. I’ve deleted and installed again my theme. No use. Earlier I have hade WP stateless and transferred media files to Google Cloud, but deinstalled plugin and went back to media on server. Can this have something to do with.

When inside posts, there is something which require all my CPU. Any idea what’s wrong here?
