Please help me

Try to use the transformers of stringer without a specific version. Then select string encryption transformer before hideaccess

I also tried, but I had an error with HideAccessTransformer, when I will be on the computer it will send an error code

Maybe there is another obfuscation at work here as well which got applied after stringer.

If the file you try to deobfuscate can be uploaded or linked with respect to copyrights (see #653, also this repository was being targeted by dmca multiple times in the past due to such issues), I could take a look at it.

When I saw a code of this Minecraft plugin in Intellij IDEA I saw Invokedynamic. AM I must add this to config?

For stringer the stringencryption is first thing to undo in 99% of the cases. I mean you could try to play around with different transformers to see if there is one stringer decryptor doing work without failure. What does the detect feature tell you?
