Hi Stanislava,
The screenshot shows that the version is 1708 but not 1811. Semi-annual channel is now on version 1803 (Build 9126.2336) right now. If you haven't, please try to update to the latest version and see if it works.
For your reference:
Update history for Office 365 ProPlus (listed by date)
Additionally, we would like to know whether the issue happen with different versions on different computers in your organization?
If that is convenient for you, can you check whether the issue happens to your Home computer? Sometimes, the same issue only can happen on computers in the organization because those computers are all controlled by the Admin, the software updates or installations can be same in this scenario.
That means, the issue is possible replicated on multiple computers in this scenario. And we will appreciate if you can help us troubleshoot the issue with a completely re-installation on a computer to see the result.
Lastly, we would like to confirm whether the project you're editing are local projects, or a project created in the Project Web App?
Thanks,
Rena
