The version of julia extension I installed is 1.127.2. Any idea to solve it?

[Yue-Wang-qvp]

Finally, after a long-lasting search for possible answers online, I resolved the problem by myself. On Windows 11, it mush be that

1. The environment variable "JULIA_DEPOT_PATH" must end with" ;" (Windows 10 has no such limitation).
2. The user environment variables "TEMP" and "TMP" must not contain the space symbol at all. (That is the critical setting I was beset with for a long time !!! Windows 10 or Julia old version 1.10.× have no such limitation.
