Try to open it in explore and re import. Same thing happend to me and i tried that it worked!

If a script is missing, look for a hidden .TMP file in the same folder in the file explorer. Change the temp file name to “Your_Missing_Script_Name.cs”
For instance, let your missing file be helloScript.cs and the temp may look like helloScript412315.TMP; Now change the temp file name back to helloScript.cs.
And TADAAAA… your script will be back in unity!!!
