You've limited options
Seek injunction 60k legal fees unlikely to succeed
Receiver won't negotiate
Personal insolvency likely best option but would need a lot more info vals if assets, other debts, information on personal private residence...risk it may not work either buy you have to try because of above.
If you've equity and can't get restructure you might have to sell to get best possible price
I know of cases when Receiver once sell for 23k when worth 175k, 66k when worth 145k, they then chased for shortfall
