This position is lost for white. The rook get trapt within its own pawns and the knights is able to incarcerate the rook for the foreseeable future.

[d]r2qrn1k/5pp1/2p4p/1p1pP3/1P6/2B1P3/1Q3PPP/1B2R1K1 b - - 0 1

White has sufficient compensation.

[d]rnb1r1k1/1pp5/p5pp/5p2/7P/BP4PN/P1P1PPB1/R5K1 b - - 0 4

Black is better | -1.00

[d]2R1n1k1/pp2rp2/n1p3p1/7p/2P1p3/1Pb1P1PP/P4PB1/3R2K1 w - - 0 21

White is slightly better.

[d]5k2/pp3nbp/6p1/2p2pP1/b4P2/4P2P/1P1N4/2B1K2R w K - 0 23

White has problems with his king position and this provides Black with
ample compensation.

White's 4.e4 was blunder, wasn't it, Jon?

Here we have output after some FW-BW and 4.Rd2 instead:
