Another user here talked about this, there were some other reasons. Most of them are selfish, I think the main one was that the second round of the municipal elections, Lula probably did not go to the meeting and vetoed Venezuela and Nicaragua (Actually I could not find articles about Nicaragua though, and someone said it was not even the final list, it was just a pre-list) so his own party and coalition did not have more problems because of Lula's meeting with Putin and Maduro (They did ok in this election, I think they just had a big defeat, but to be honest it was a difficult election for Lula's candidate to win. A pleasant surprise was the victory of the Workers Party in Fortaleza and in the South, before a very pro-Bolsonaro region, but which has a large presence of the left due to rural workers), the Workers Party having an unexpected runoff against the Liberal Party (Bolsonaro's party) in the Center-West, a region that the Workers Party was never strong.
Pretty shitty of lula really, you can tell Lula decided to punish Maduro over not cooperating with Brazil about the election results.
Over not playing along with Brazil’s farcical and condescending patronizing bullshit*
