What happens if you would add a charge to a running system that has a low charge on a 404a system and you charge thru the suction as a vapor. I had a memory lapse and have charged 410 systems as a liquid thru the suction side with success . after realizing what I did I shut system down and recovered charge changed filter drier pulled vacuum and closed king valve and charged system as a liquid on high side .the compressor is a Copeland scroll

You half done it right the first time. The half getting past is charging with vapor instead of liquid.
404a is a blend of three different refrigerants, each refrigerant has its own pressure at a given temperature, also turn to liquid or gas at different pressure and temperatures. 404a In the liquid form holds its ratio of blend quantities, but not in the gas form. This is why we handle blend registrants in the liquid form, to maintain its properties.
What you did, charging gas, meses up the refrigerant both in the refrigeration circuit and in the refrigerant container or jug used for charging.
After charging like you did the first time, with gas, I would have removed or recovered the refrigerant from the machine, vacuum it some, then recharge with fresh new 410a. Done. The first refrigerant jug you used to charge gas out of is damaged, useless, send out back where they handle registrants in that condition.
Beware to not let liquid in the low pressure side too fast to avoid flooding the compressor to avoid internal compressor damage.
There is a device called tm Quick charge, it relates the volume of liquid used when charging. I don't use the device though I own one, just keep an eye on how cold and frosted it gets in the compressor suction tube area.

As long as you recovered the charge, pulled a vacuum, changed the filter/dryer, and added the correct amount of refrigerant as a liquid, you should be good to go.
