If your development machine is air-gapped, you can still apply the patch manually. The patch script essentially replaces a few key binaries. Here is the manual method:
You downloaded the wrong patch version. Fix: Double-check your Vivado version via vivado -version . Download the exact match.
The is an essential fix for a major date-related bug that paralyzed FPGA development workflows at the start of 2022. Known as the "HLS Revision Overflow" issue, this bug causes Vivado and Vitis High-Level Synthesis (HLS) tools to fail when exporting IP, as the internal date-based versioning logic cannot handle years starting with "2022".
