Hi,
as described there [Bug]: Anchor parser in URL 0e20a6f breaks LV2 x42 plugins loading. · Issue #1236 · juce-framework/JUCE · GitHub
I guess some symbol in LV2 port names leads to crash after this commit URL: Add support for anchors in URLs · juce-framework/JUCE@0e20a6f · GitHub
after I reverted it then x42 plugins loads fine
