What could be the problem with "object property or method not available" in vb?

I just came into contact with VB and want to debug a program bug. What is the problem with this similar prompt? Thank you!

It should be a "point operation" to access non-existing members, for example you can write Text1.text, because Text1 has this property; if you want to write Text1.Caption, this error will occur ...

Can this problem not be found during compilation? I appeared during execution.

Use CTRL + F5.

This error occurred only after the program ran for 7 to 8 days on the site. I couldn't find it directly by debugging. I just wanted to know what might go wrong. Thank you!

For the object that is bound later, it cannot be found at compile time ~
It is recommended to check where the object type and Variant type are used ~

It may be like Text1.Text="1", but Text1.Enabled is already False and this error will occur.

No initialization class

Or the recordset is not open

etc.
