This KB article provides information to remediate/delete a failed traffic group (TG).
Symptoms:
Whenever a Traffic Group (TG) creation fails due to any reason (mostly due to compute resource crunch, etc), the TG creation shows up as Failed.
To understand the cause, hover the mouse over i beside Failed.
Most of the times a traffic group (TG), deployment fails due to insufficient resources on the SDDC or due to anti-affinity rules blocking the TG VM to power-ON on a given host.
We recommend deleting any failed TGs from the SDDC to ensure they won't pose any risk to upgrades.
Steps to delete a TG:
Workaround:
Failed TGs do not carry any live traffic; therefore, we recommend deleting them instead of following any workaround.
Refer VMware Docs:

Impact/Risks:
If the failed TG continues to be in the same state, upgrade pre-checks identify the failed TGs and block the SDDCs from upgrading. This results in delaying the upgrade cycle for the SDDC.
