Hi, thanks for the report. I've read through the linked PRs eclipse-theia/theia#10734 and the ticket eclipse-theia/theia#10728 on the main Theia repo.
Is it possible to build Blueprint with node 16 and the merged changes or is there anything we have to adjust in our build files here?

@Alnyli07, try to wipe the Theia CLI cache folder. It's under $TMPDIR/theia-cli/cache/.

It worked for me: eclipse-theia/theia#10728 (comment)
