Have another $200K to invest in. Should I put another $100k all in VTI right now?

Have another $200K to invest in. Should I put another $100k all in VTI right now? I’m a little worried because of the war.

Current portfolio: $726K: $426k in VTI and $100K in AAPL, and $200K cash.

Additional info: 42yo with paid off house and zero debt. have another $190K in an HYSA. I think I will be taking a year off after this year because I will be closing my business due to stress and very low revenue. Will be starting another small business after the 1 year sabbatical.
