    you could try to heat up the  bolt and  soak it with a release agent (WD40 and similar)   try to rotate both ways  and  resoak   ..repeat

    takes patience

    drilling with  gradually increasing drill sizes  will eventutally weaken  it but don’t  drill out the threads !

    you can also try  extra cold  from a simple  Dollar store keyboard  spray can inverted.   the stuff will freeze  quickly and may break the bond.
