It appears and error that does not exist

 I am using VS 2022 Community  and when i develope asp.net apps it happens sometimes that it appears an error that does not exist adn only after many hours of searching for the error or rewriting the same code the app begins to run correctly. Somehitng simmilar happened to any of you ? how can i avoid these strange behaviour of the compiler ?

Thank you in advance
