I used: 2023-03-23
As per a youtube video guide, this fixed the problem.

Could someone from the YosysHQ team please comment on what causes the problems in newer builds? Are their plans to fix it? Do you need input from users?

Can you describe what the problem actually is, beyond a vague reference to a video? And what operating system you're using?

IMHO the warning to use the old version of OSS-CAD-suite stems from this tutorial: https://learn.lushaylabs.com/getting-setup-with-the-tang-nano-9k/

There are some synthesis issues in the latest version of OSS-CAD-Suite while they are going through a redesign of the OSS toolchain. It is recommended to download the 2023-02-10 version of OSS-CAD-Suite for best results: https://github.com/YosysHQ/oss-cad-suite-build/releases/tag/2023-02-10

I'm not experienced enough to verify whether their statement is correct. I've tried a tiny test verilog project with 2023-02-10 version, 2023-03-01 version and 2023-04-01 version. With the latter I had the most problems, but different ones than the warning states: failures to upload to the Tang Nano 9k. Probably because of the output of NUL-characters I can't copy paste the full log.

I've also tried with a build from today, but it looks like Lushay Lab's VSCode plugin is not compatible with the latest builds of OSS-CAD-Suite because it seems to miss some bin\gowin_*.exe files.
