pnpmInstall: Throws strange exceptions: Solved with "--no-parallel"

I get these exceptions when calling gradle pnpmInstall from my project root (with several sub projects configured for pnpm):

 ENOENT  ENOENT: no such file or directory, unlink '/home/johannes/projects/com.cedarsoft.monorepo/node_modules/.pnpm/node_modules/tunnel-agent'

The exact error message changes every time:

 ERR_PNPM_LINKING_FAILED  Error: ENOTEMPTY: directory not empty, rmdir '/home/johannes/projects/com.cedarsoft.monorepo/node_modules/.pnpm/shikiji@0.9.19/node_modules/shikiji/dist/langs'

 ERR_PNPM_LINKING_FAILED  Error: ENOTEMPTY: directory not empty, rename '/home/johannes/projects/com.cedarsoft.monorepo/node_modules/.pnpm/postcss-calc@8.2.4_postcss@8.4.33/node_modules/postcss-calc_tmp_15783' -> '/home/johannes/projects/com.cedarsoft.monorepo/node_modules/.pnpm/postcss-calc@8.2.4_postcss@8.4.33/node_modules/postcss-calc'

The exception does not happen if adding "--no-parallel".

Reproduce the gradle pnpmInstall failure in a project with several pnpm subprojects, then compare it with the --no-parallel invocation. Investigate the pnpmInstall task's parallel execution and verify completion without ENOENT or ENOTEMPTY linking errors while retaining parallel operation.
