This just happened to me. Last week I was editing a (versioned) polygon layer, this week I get that error and can't edit *anything* in my production (SQL Sever) DB. Tried different machines, different Projects, different FCs. Haven't tried re-versioning, I'll have to do that off-hours.
The technical help doc is classic -
https://pro.arcgis.com/en/pro-app/latest/tool-reference/tool-errors-and-warnings/160001-170000/tool-...
Anyone have ideas? I'll contact tech support but based on the document above I'm not real hopeful.
Thanks,
Tycho
