1. Open VMware Fusion
2. Remove multiple virtual machines
The text is obfuscated by the scrollbar, which is set to always appear in the macOS settings. Also, the "Failed to remove virtual machines." text should probably not include trailing punctuation as it is a title.
The issue is present in 11.0.1 Beta (20B5022a) but also exists in macOS 11.0, which will most likely be shipping with Apple Silicon Macs.

Seems a UI issue on Big Sur, will forward it to development team. Thank for reporting.😀
