Localization, Multiple Reviewers in Same Language

I have multiple reviewers working on validating a Rise translation of one course into Brazilian Portuguese at the same time. The second reviewer received the following error message pop up in the tool: "Editing it disabled due to an error. Please ask the course creator to update translations and republish."

What is the least disruptive thing I need to do to resolve this?

Can I just accept the translation edits from a 1st reviewer? Or do I need to republish the review link and resend it to the 2nd reviewer before the 2nd reviewer can start validating? Note: We're not adding reviewers manually; we're sharing as a link to all reviewers.

Right now our work around is having the 2nd reviewer add their edits in the comments, then I can manually go in and update. But this isn't feasible when we have hundreds of updates.
