Lib not found with last versión Core change? Home change? Framework?

I’ve seen this type of error several times now, and they all comie down to using an old version of platform-espressif32 with a newer PlatformIO core. Several users report the issue is solved by a reinstallation of PlatformIO (remove ~/.platformio and restart VSCode). See Xtensa-esp32-elf/bin/ld.exe : Cannot find library.
