Transaction is stuck for 3 weeks (samurai wallet)

Hi, Ik made the mistake of giving a low fee with my transaction of 2 sats per byte in samurai.

This was a full spend and RBF was disabled by default (samurai) .

Samurai wallet has CPFP enabled but this results in a error "cannot create CPFP transaction".

I just transferred some bitcoin to that same source wallet so I can spend it to increase the fee but it's still stuck and gives the same error.

Transaction id: 20219dccb325863160e9f94da9791c921201771c5c9a8118d56b962dfe89b4ab

How can I fix this and are transaction accelerators een option? Viabtc asks 300 (0.01btc) dollars so that is not an option.
