Remove #words attached

[Alo99]

I want to remove hashtags # that words are next to the # with out removing the rest of the file name.

For example:

FROM :
2025 07 27 A #motivation #psycholgyfacts #psychology #english #habitsthatchangeyourlife #psychologyfacts .mp4

TO:
2025 07 27 A .mp4

This works I can do this but what I want to do is

FROM:
Modern Family - Phil Manipulates #shorts Haley And Alex .mp4

TO:
Modern Family - Phil Manipulates Haley And Alex .mp4

NOT:
Modern Family - Phil Manipulates.mp4

If I am in R3 and type in #* > Replace, it will delete the rest of the file line name. Not the hashtag and word beside it.

Is there a way for the above green line?
