From the picture of the photograph which we have seen, the print damage appears to consist of blank areas on the print.
Therefore either those areas . . .
a) are not developed,
b) or they received massively less exposure,
c) or there is no sensitive emulsion on parts of the paper (caused either before, or during or after the processing??),
d) or some combination of the above,
e) or ??? Any other possible causes anyone can think of ???
Do a "Sherlock Holmes" to confirm or deny each possibility and you will have the result.
At least some of the red, low-wattage, decorative LED bulbs are paper-safe (I have a couple myself). They are also cheap enough to try a couple and test them on their own, in a corner of your darkroom with the other lights off - if they work adequately, then you have a useful and long-lived alternative safelight bulb. Note that not all papers are actually safe under an amber safelight so for a group darkroom, with almost any possible choice of material used from day to day, it will be better to choose a red light or filter - even though the illumination is a bit less "bright".
