There is no benefit in having such a large anchor only negatives including putting far too much strain on the windlass. If it is the original windlass it is probably a Cayman with an 8mm gypsy that takes Lofrans chain.

We have the same windlass in the same or similar installation with a 25kg Lewmar Delta on 8mm chain (65m), and it never jumps off the gypsy... So it can't be weight, I would agree with Yngmar, it must be insufficient chain in contact with the gypsy..
Yngmar:
Found it - it was on PBO: https://www.pbo.co.uk/practical-projects/stop-chain-jumping-anchor-windlass-18946

DIN and ISO chains have from 10mm onwards slight differences in length that can make a huge difference in windlass efficiency under heavy loads: check a good match between gipsy and chain.
On mine, I found out when I bought my boat, in 15m deep waters, that chain (10mm ISO) and Gipsy (8mm ISO) were not matching, although it still had enough grip in shallow waters (!!). So I changed the gipsy for 10mm and happy life again.

I'm not really surprised, we have 30m and 35m of 8mm chain connected with two 'Wichard' shackles, they generally happily jump over the gypsy without too much drama...
