Hello @Junior Souza
Welcome to Q&A forum!
I totally understand that you have purchased and you need to have full features of Microsoft Teams to support your work. In this case, I will try to help you double-check by several troubleshooting steps, but I also need to clarify that as we are only forum moderators, we are not authorized to access the backend user data and affect the product settings to support you.
I suggest that you try from step 1 to 3 in order to see if this issue still persists:
1/ Run System File Checker
In the Command Prompt window, type the following command, and press ENTER:
sfc /scannow
Warning: Do not close this Command Prompt window until the verification is 100% complete.
The sfc /scannow command will scan all protected system files and replace corrupted files with a cached copy. The scan results will be shown after this process is finished.
Use the System File Checker tool to repair missing or corrupted system files - Microsoft Support (Step 2)
2/ Reinstall your Teams
Uninstall Microsoft Teams - Microsoft Support
Reinstall Teams:
- Visit the official Microsoft Teams download page.
- Click Download for desktop and run the installer.
- Follow the on-screen instructions to complete installation.
Download Microsoft Teams Desktop and Mobile Apps | Microsoft Teams
3/ Update Windows version
Settings -> System -> Windows Update
4/ Roll Back Window Version
You can follow this article guidance to go back to Go back to the previous version of Windows - Microsoft Support and double check if this issue still persists.
Hope this information will support you move forward.
Please let me know if I can do anything more to support you!
