This issue is limited to users who are on devices that leverage
certain versions of Intel driver 32.0.101.69xx (including but not limited to,
32.0.101.6913, 32.0.101.6987, and 32.0.101.6989). Impacted users may see that
Microsoft Teams freezes for some time, and then it automatically recovers. For
those that need immediate remediation, our telemetry indicates that version
32.0.101.6790 of the Intel driver reproduces this issue the least.
Affected users can use the Microsoft Teams web app as a workaround until this
issue is addressed.

access Teams channels due to the icon not being present in the left panel.

creating this dataset.
While we’re focused on remediation, users may have been able to use the July
2025 or previous version of the Power BI Desktop to avoid the impact.
