    Will this fix be backported to 2019.4 LTS?

    Just a quick note for anyone watching this thread. Unity support let me know not to revert back to 22 as it could cause package corruption. They also said there aren't any work arounds identified at the moment for the problem.

    Has anyone tried to revert back to version 22 perhaps? It doesn't show that version as being affected by the bug. Is that a workable solution for now?

    Upgraded from 25 to 26 and this error is now pretty consistent it did used occur in very sporadically in previous version, not enough to worry about.

    Have had this issue a lot since upgrading to 2019.4.24f1 from a previous 2019.4.x version. Doesn't happen every time but darn near every time.
