Hello Adrian,
Thank you for coming to the forum.
Can you try the below. Do an office update and an sfc scan on your device. Then do not mind repair the office once more and see if the issue persist.
A) Update
- Click Start
- Type Windows Update > "Click Windows Update Settings"
- Click Check for Update
- After the Update Check is done, Click download and install for all the update
- Reboot your device
B) sfc scan, see the steps below.
Click start and type CMD. Click Run as Administrator and in the terminal window type sfc /scannow
Please wait for it to complete and reboot.
C) Repair office
- Right Click on Start > Select Installed Apps or Apps and Features
- Scroll down until you see Microsoft 365 Apps (or your office version)
- Click the three buttons beside the Microsoft 365 Apps (or your office version)
- Select Modify
- Click Online Repair (this will take a while to be done)
- Restart the device
