Where do these switching problems come from? (@Steffen, please also look inside!!!)

Hello, I’m trying to tell you what they look like at the moment. And how this was done earlier. At present I have massive problems to switch from the 1st to the 2nd gear in the morning…The resistance to insert the gear is so massive that you have to tear the stick in…It’s going to crash so wonderfully in order to avoid the “crashing”, I’ve noticed that you have to switch off from the 1st to the idling and then down to the 2nd gear. Then it doesn’t crash anymore, however, d it is still very massive when inserting the gear…All other gears can be inserted quite normally, but also with a slightly lower resistance (and without crashing) …When the car was moved by 10km, the cracking has disappeared when inserting the 2nd gear. However, the whole switching scenery can still be switched very “crazy” … In the past I did not have any problems in cold or warm condition…Every gear, whether switching up or down, read itself without The complete opposite of what is currently in demand… But what can these problems be? I don’t believe in worn-out synchronous rings, as they don’t break from one day to the next… Last year in December Steffen and I changed the clutch, could something have gone wrong? Does the clutch possibly not separate properly? What could this be? After the clutch change, the Sc After that, these problems had disappeared almost completely for a short time, but are now there again… Could it also be that these switching problems come from defective engine bearings? The engine had to be tilted to the rear when the gearbox was removed, maybe that gave the engine bearings the rest? And now the engine and transmission move so strongly that it is no longer possible to move a gear. future? I am greeting with my Latin at the end
