Unity ProBuilder addon meshes causes "Hold on busy..." issue

Question

I am developing a project with Unity and during the development of this project, I had to create a model community by combining a few models, this time I was having a problem with meshes, so I used the ProBuilder plugin to combine the meshes of the models in a very simple way and my problem was solved very smoothly. But after all the models were finished in a way I never knew what triggered it (average half an hour 1 hour) I noticed something strange in the editor. I started to get the “Hold on busy...” screen frequently while switching between models in the editor (especially the models I applied mesh merging with probuilder). Guessing that the problem was caused by probuilder, I deleted ProBuilder and the problem was solved, when I restored it, the problem came back the same way. After doing some research I found out that it might be a problem with Cache and I deleted the Cache files completely. But again there was no difference. I updated Unity version 2022.3.521f directly to Unity 6.0.0. I deleted the meshes of a few models and created them again (because I figured out that the problem was caused by the meshes created by probuilder. ) There are no more waiting times in transitions between models, but there is a very small delay, but the main problem is when I try to switch from Editor mode to Play mode, normally 1.5, 2 seconds of play mode transition now ends between 1 minute 27 seconds and 1 minute 35 seconds. ProBuilder is an important plugin for me, what could be the cause of this problem, how can I give you more details or how can I get help with this problem. Obviously my way is to solve problems by learning in depth, not bypassing them.
