Similar problem with essentially the same solution. Just cross-posting it here in case it helps anyone: [Julia 1.9, same depot with different machines?](https://discourse.julialang.org/t/julia-1-9-same-depot-with-different-machines/103463)

There is also the environment variable [`JULIA_MAX_NUM_PRECOMPILE_FILES`](https://docs.julialang.org/en/v1/manual/environment-variables/#JULIA_MAX_NUM_PRECOMPILE_FILES), which someone in this forum suggested to set to a higher value (e.g. ~50) if disk space is not a big issue. It does seem to help in my case (heterogeneous cluster machines) to reduce the number of potential (re-)precompilations.
