以前用的 idf4.4 编译的，今天升级5.0 后出现这样的问题：

OJECT_VER.
-- Building ESP-IDF components for target esp32c3
-- Project sdkconfig file H:/esp32test/esp32c3_test/template-app/sdkconfig
CMake Error at H:/esp-idf/tools/cmake/crosstool_version_check.cmake:37 (message):


Toolchain:
C:/Users/xy/.espressif/tools/riscv32-esp-elf/1.24.0.123_64eb9ff-8.4.0/riscv32-esp-elf/bin/riscv32-esp-elf-gcc.exe,
crosstool-ng version 1.24.0.123_64eb9ff doesn't match supported version
esp-2021r2-patch3

Please try to run 'idf.py fullclean' to solve it quickly.

Check Getting Started documentation if the error continues.

You can override this error and proceed with build by defining the
IDF_MAINTAINER environment variable.

看起来好像是工具链没选择正确，现在文件夹里有两套工具链 一套是1.24 另一套是 2021r2-path3
请问工具链是在哪里指定的？
