Without knowing the source of this money or your entire financial picture, it's impossible to say what I would do in your shoes. At 60, you are much older than the average person on this forum, who has 30 or more years to catch up with you. What they would do would be much different than I would do, and we are similar in age.
If this is a rollover of a lump sum pension, I would develop an overall asset allocation, and start investing. Since sequence of returns risk applies to you more than a young person, I would be cautious and move into the market slowly.
If this is not money from a qualified retirement plan, I would consider the ultimate purpose of the money. The time horizon would govern my investment selection and timing.
